Need Supra Help ASAP!!!

[UhOh5o]

Here is my current issue with my 87 7mge

I went out of town for the weekend with the car I drove 200 K to medicine hat, alberta.

After I got here I let the car sit for awhile and then went to start it up and it was missing horribly, felt like it was running on 2 cylinders, then stalled. I started it up again and kept missing then went back to running perfect.

The car has now done this to me 4x, but once it quits missing it runs perfect, no issues at all with power or anything, and almost seems like it is just when I let the car sit for awhile, but doesn't happen every time.

Can someone please give me an idea of what they think it might be since I leave to go home tomorrow.

Thanks very much.

check the plug wires - sounds like they might be grouding on something.

+1 to funky's post. id have a look in the spark plug galley to check for leaking coolant, pooled oil ect, i'd check also check the spark plugs are tight and wires in good condition. Never hurts to have a look inside the cap, ive had moisture in there on a 4ag once and caused missing. also never hurts to check for any codes might have been thrown, i keep a bent piece of wire in the handle of the battery to use as a check connector when needed.

one more thing, i've been told im overly anal about this but i feel plug wires shouldn't touch too much, especially going long distances in parallel..

good luck!

A few weeks back I was adding oil to the car and spilt it all over, I had nothing to clean it up since I was in the middle of no where so I had to leave it :frown: Then when I got home I cleaned it as well as possible from around the top of the plug wires and everything.

Now yesterday I pulled the 2 plugs at the front to see how they looked and sure enough they had oil on them, so I cleaned them up then re installed them and tried to clean everything out as well as possible.

I did notice oil though in the plug gallery and also tried to clean that up as well as possible, can anyone give me any ideas or tricks on how to clean that out?

So now Today I went out to the car after letting it sit all night, it started perfect, I then drove into the city and left it at the mall for about 40 minutes, went back out to start it to having it miss again till I drove it then it all went away and ran perfect... Also can someone please tell me how to run the CEL codes?

Thanks for all the help so far everyone.

Feminine hygene products.

TSRM page FI-23 (http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=FI&P=23).

[Dexman]

if there is still the spark plug galley cover - remove it (i know this seems a hassle as you have to remove the intake Y-pipe and all the other fun stuff in the way) to the job proper your going to have to get in there and clean it up to eliminate it as a source of your engine miss.

Dan I never thought to use feminine hygiene products but that sounds a great suggestion. I gave my 7M a good pressure washing once and had a hard time getting all that water out afterward, i was using compressed air and paper towel and it took some doing, but a tampon is super absorbent- great idea.

UhOh5o are there any other symptoms aside from the miss on hot start? Loosing any coolant? Could the problem be from heat soak? Try driving it until it's hot then park and leave the hood open, let it cool like that then try and start it, if that cures it then ill tell you how to cure any kind of heat soak problems.

There is no cover, that is why the oil went all over the top of the plug wires on me.

As for the heat soak, it is a 7m-ge I do not have heat soak issues.

Like I said, the car ran perfect before I came up here, now it does this only once in awhile when I start it up, I am thinking it is due to the oil in the plug gallery... Has anyone ever tried using brake clean to clean something like this up?

Any one else have any other ides that are non smart ass and helpful?

Thanks very much!

[Dan_Gyoba]

a 7M-GE does get heat soak thanks. My underhood temps with the GE were worse than they've been with the turbo. The only time I had problems with that though were in very hot weather.

Well it is +1 when this happened so I don't think that is the issue... I am thinking it is the oil on the plug causing the miss currently...

And even when the car was shut off for 40 minutes + and I went to re start it, it still had the missing issue until I drove it then it all went away...

I also was thinking that maybe this could be due to a bad valve cover gasket, what do you guys figure?

[Funkycheeze]

That is usually how oil ends up in the galley like that.

[UhOh5o]

Yeah, I was just maybe thinking before it was cause of all the spilt oil on top of the plug wires since the car never had a cover...

Now running it like this is there a chance of wrecking the car, other then fowling plugs... Or is it safe to drive it home under these conditions?

[Piggity]

I wouldn't be driving it like that if I were you. Anytime the car misfires, it could be causing your engine damage inside.

[UhOh5o]

Even though it is just when I start the car then it goes away fairly quick? Like I said the car does not missfire or anything while driving, it still runs perfect. I am asking because I need to go home tomorrow for work so I am trying to figure this out.

[Funkycheeze]

the extra fuel isnt good, but its not going to make short work of the engine. Sounds like you need new valve cover gaskets.

This is a common 7m problem.

Forced bird injection!!!

[Dexman]

hey Uhoh this might sound stupid by check that the screws that hold your valve covers down are in fact tight, more than once I've found loose valve covers screws on old toyota engines.

I'd also suggest a thorough inspection of the engine. Check for simple and easy things to identify from outside the engine. cracks and leaks along any part of the intake, leaks for water to get into the AFM, cracked/worn out injector seats, leaking fuel, coolant, oil, missing vacuum lines, or cracked/abraded lines. same for all of the electronics. basicallly the same thing you do when you are looking at buying a car. Have a good look with a flashlight at all of the components to verify no deficiencies. I'm sure the oil in the galley isn't helping, but it sure doesn't hurt to give your engine a good look.. even after that issue has been addressed.

I was in a junk yard a few weeks back and was taking a fuel tank out of a toyota truck. I noticed the truck had a brand new carb, new air filter, brand spankin new fuel pump, new fuel filter and even another nice looking carb sitting on the passenger seat. While taking the fuel tank out I discovered a crack in the fuel line coming off the tank. I would surmise the owner was having problems with fuel pressure and replaced all of those parts only to have the truck still not working properly, so he junked it! Goes to show the value of proper diagnosis.

best of luck

i had the same problem 2 years ago, my cam covers were leaking into the valley, to make it worse, i washed my engine! lol, it would miss, then run perfect, if you can get your hands on some pressurized air(shop air 100psi+)1 repair the cam cover leak (i talked to toyota to get some new bolts-not stock ones, replace those screws with some real bolts! those gaskets are something like $20-i can't remember the price)2 after repairing your cam cover leak wash all the oil off your engine with pressurized water, and engine shampoo (if you can get ahold of it) just blast the crap out of everything thats dirty! 3 remove the plug wires and the plugs completely, 4 dry everything with compressed shop air(if you have access(don't do this if you can't get ahold of shop air) 5 replace the plugs, and while replacing those plugs, blast air into the cylinder the plug is out of, to get anything out of there, 6 re-assemble everything with proper torque, 7 look for any other engine leaks.

i wouldn't worry about driving it, it should be fine, i am currently running mine with torn motor mounts, (waiting for parts lol)
fret not.

I have had some experience with this, a couple of things to check, one if there is still oil in the valleys get that out of there, the way I do it is a can of brake clean and a blower on the end of an air line, it gets messy but it works you shove a rag over the hole fill er up with brake clean and pfffts blow in and the rag catches most (hopefully) of the oil. I would also, when it's running smooth take a spray bottle with water and spray a light misting of water over the plug wires see if it starts to miss, if it does - plug wires, do the cap and rotor at the same time. if not, we move on, the issue that I ran across a couple of times (rarely) was the cam sensor. As your engine is hot and heat equals resistance electrically, sometimes the pickup module in the distributor would sketch out and send no primary signal to the coil pack. Unfortunately you need a noid light to check primary signal, but if your secondary checks out all good, I say its a primary issue. FYI if you need the flash codes and base timing out of your computer jumper connector T and E1 on the "Diagnosis" connector on your left strut tower. The only other guess I would have is, although I hate to say it, head gasket, when the engine is hot and the cooling system pressurized it's possible that it is pushing coolant back into the combustion chambers and missing as a result of moisture in there. But on the GE I would go with ignition first. Hope this helps, if you need any other help lemme know.... Get er fixed so you can enjoy it again!

[Speedysupra]

And good call on the 10mm head, 8 mil, bolt replacement on the cam covers Uncorkedsupra, that's genius the philipses were always coming loose... Only I would advise against running a car with a miss, three reasons:

1. Unburned fuel going through the catalytic converter is hard on it.
2. Unburned fuel washing down the sides of the cylinder washing the oil off the rings and skirts causing scoring and eventually oil burning
3. It sucks to drive a car with a miss when you are used to driving a silky smooth supra baby!

[Dan_Gyoba]

Those are 6mm by 1mm thread bolts for the cam covers. For those reasons, at least I don't have to worry about #1 myself, though I would still not want to leave an ignition miss alone.

[prairieboy84]

check the seals on your injectors if one of em is gone or going itl cause the engine to do funky stuff also could be a vacuum leak

and if your wanting to turbo ur 7m first choise auto wrecker has some stuff from a white 88 targa and max machine has from what he told me a good ct26 all the rest of the stuff i drive the copper mk2 in swift it burns more oil than gas right now but i love it

Hey everyone, ended up being just a simple valve cover issue but thank you all for the help.

As for the 7MGTE at Hilders, the engine is toast, it was my friends car and at absolute least it has a spun rod bearing, the car lost all it's oil and was still ran so there are some major issues there.

As for a CT26 I still know where the original is from that Supra and it has very minimal shaft play but not sure exactly how it is since I haven't taken it apart.

As for your MK2 I have never even seen it which is crazy, Is it a Terra Cota car? I use have an 83 Terra Cota Supra and a 85 Black on Black Supra in town.

I see your from Medicine Hat, did the car ever sit by Domino's and is it an 82 ish? Auto?

[prairieboy84]

no im from swift i tried to put that in the location box when i signed up but it wouldnt let so i put the hat and i used to live there so it kind of works and good to know about the supra i was looking at it for some of the stuff on it but if it was run dry then ill stick to ripping out the rear end lol

i just got the car been trying to stop the oil leek isues the best i can for now im down to the cam seals but i cant copper rtv that so i need new ones of those and camtowers and a exh mani but that come in time but i did just find a apexi dunk megaphone in a wrecker yard with less then 6 mounths use for dirt cheappppppp but now that i have it and messured after i bought it im gonna have like 3 inches in the back ground clearance under it

i dont have plates on the car right now but with in the next few days itl be on the road again smokeing lol and its an early 84 5 speed all bone stock except for the honking apexi out the back wich is goin on tommorow

Just a thought but why not do a 7mge swap or even pick up a 6mge from Rapidchimp?

If I still had my MK2 after driving this MK3 I would have done a 7m swap much sooner, this car is 500 + pounds heavier and pulls much harder, IMO the swap would be totally worth it, a very cheap swap and 7MGE's can be found anywhere.

As for that rear end, yes that would still be decent enough, and it was an AUTO car so it it hasn't really had a hard life.

I cant wait to see another Supra in Swift, I have been pretty much the only person around who ever had MK2's and my current MK3.

As for your exhaust issue, that may suck with our roads, I know I smack my fart can quite a bit on my MK3 and there is a fair bit of clearance there.

If you ever see me out feel free to flag me down, would be nice to have someone to b.s. with about Supra's!

[prairieboy84]

yah i know who you are u your stang is fucken nice we went to school together my last name is monette i used to drive the black cavy with batman wing and halfass baretta rear conversion but anyway my hopes of getting on the road this week just got post poned i got a partial rebuild kit comeing in for it so im gonna yank the motor tear it down port the head and swirl polish the valves and put her back in the rest of the motor except the cam towers and exh mani is good i love my 430 gears but its to much for everday use the 370's in the white one or another mk3 rear end would be alot more practical ill loose power but my engine wont turn @ 4 grand on the highway all the time lol my engine was leaking oil so bad that the alt is a clear brownish color and on the pass strut tower and hood above it have oil sprayed on em but i think that is mainly from my rack & pinnion and a 7mgte swap would be sweet but right now other things are more important after i sell i dodge im varying my options

my other daily driver is a lowered silver 87 d150 its got comp valvetrain w/t 480 lift cam, fully worked fast burn heads, headers w/t duals, 727 torqueflite tranny and im trying to sell cause even though its got a top end rebuild its still slow as fuck i top out at 130k in the 1/4 and it gets 10 miles to the gallon mostly due to a 1100 torque converter, slow valve body, 270 gears in the rear i used to own a 90 300zx till it went to the dogs that was a fun car

ill also try and get some pics on here only mk2 around that ive seen or know of in coppertech burnt orange with black center two tone

[Tara]

Not to be rude, but please use proper punctuation, capitalization, and the "enter" key... it will make your posts far more legible. Run on sentences in a block of text rarely allow for the author to be taken seriously. Try to separate one thought from another.

Thanks, and once again, welcome to the club!

[prairieboy84]

lol ok i apologize i was never very good at punctuation i completely bombed english and never finished high school lol ohhhhhhhh the good old days now im paying for it
ill try and make my posts more understandable but if i dont just kinda bare with me

[Speedysupra]

Oh, I absolutely agree with Tara. Proper punctuation, capitalization and all round grammatical correctness are crucial to ensuring your thoughts are communicated directly and without prejudice. FYI, I did not fail English. And unfortunately, or fortunately, for me my mom was an English major in university. "And make sure you capitalize all of your proper nouns!". Oh brother, those were the days....

We all agree with all of the text messaging, instant messaging, face-book messaging and all other types of messaging, it is difficult to maintain a certain level of grammatical correctness. So, I think we can all sympathize with an individual who struggles with the finer points.

At any rate, we will all try to read your posts as objectively as possible but with the hope that eventually you will use the period key or possibly the enter key to help separate your thoughts. Of course, the spell check feature on your internet browser may help with those little "u" for "you" mishaps.

How was that, Tara?

[Tara]

Taut pretty much sums it up! We're basically just going for "everyone gets the point, can understand everyone else's post with minimum effort." That's all!

[Got_Rice_?]

Back to Supra discussing, since this is not a grammar forum :lol:

Anyways, thanks very much! I am pretty sure I remember you from back in the day, IIRC your name is Dallas?

I would definitely like to see the car out one day, it is very rare to see MK2's or MK3's in Swift so it is always nice to see one out booting around.

[prairieboy84]

yah my name is dallas, one day itl be out again its not driveing right now well it can be but i wanna fix the oil leak issues first
and now that its winter ummmm see how it goes i guess. i wanna do this one right not like my cavy i had omfg was that thing was horrible

ive been trying to fix the ignition problem with my truck so i can sell it to some kid and the money from that is gonna fund parts for my supra then save up all winter for the turbo in the spring as well as interior

as for now i dont have a heated garage and it isnt big enough to fit the car & engine crane folded out together so i have no idea the weather is sppose to be better this weekend and now that the truck is fixed its time to give the supra a whole lot of love
