Sorry, should have mentioned coolant, flushed, new 50/50 coolant mix. The cooling system has no air in it. I do have the fans, and they seem to come on of their own accord when the temperature climbs slightly above half on the stock gauge. I havn't seen an advanced auto parts in my part of...

I got such good info on my last question I figured I'd try another! 1990 turbo supra, A/T, stock. When the weather warmed up this summer overheating problems reared their heads. What I did: New fan clutch, (tundra orange hub) rad re-core, new 180 thermostat, new 13psi cap, and while I was...

"One easy simple test to determine this is with the car running, disconnect the negative battery cable. If they car continues to run the alternator is good since it is generating enough electricity to run at an idle. It can also indicate a weak or bad battery since it runs at an idle but goes...

Ah, I see, thank you. I disconnected and plugged the line to the modulator. Thanks for the tips about the EGR jetjock.

Not sure. I'm thinking it's the modulater (I hope that's what it's called, the little component mounted right above the EGR) but the problem may be the VSV, or something else. Testing as per TSRM should tell the tale, I hope. I've been playing with cars for a long time, twenty years now, but...

Thanks for the compliment. Making people ramble around in the dark and fish for information that should have been in a post to start with is just wasting their time. (and the person with the problem's time as well) EGR for the win!:icon_bigg Thank you very much! I disconnected and plugged...

No idea when the fuel injectors have been cleaned. Not since I've had the car (few months). There is a bill in the collection from the PO for injector O-rings, so I'm guessing they were out relatively recently. CPS, I have two, car behaves the same with either one, and I don't find any problem...

1990 Supra Turbo, stock. It has a miss off idle. It idles perfectly smooth, and it seems to pull smooth under load, but it has a miss when driving at a steady speed with light to moderate throttle. This problem has worsened over time. This miss is also very apparent when free reving the...

Little pieces of tubing (I used brass because it was laying around doing nothing) JB welded to the broken off nipples worked well for me.

Shortly after buying the supra the horn quit working. Turned out it was the horn/hazard fuse. The idiot PO had been having the problem as well, I'd say, since it had a 30 amp fuse installed instead of a 15. I attempted to find a short, by installing a test light in place of the fuse, and...

Red 1990 turbo, Chilliwack, BC. (Well it's actually the wife's, but I get to wrench on it and even drive it occasionally...)

Not that I am a supra expert, but here's my take: BHG is not a big deal as long as you know what happened. If the head gasket went and then the engine was run, rather than being shut down and fixed there is the possibility that coolant got into the crankcase and it was run like that, which will...

Just a follow up, so that anyone searching for info finds a resolution. (I hate searching, finding threads, and not finding out what the solution was.) Torque converter, to be specific, a bearing going in the converter. There were no other internal problems with the transmission. Replaced the...

If it's a slide on fit there should be no problem. I withdraw my statement. I'm new to supras and was under the impression that they were an interference fit. (The need for a puller made me think that.) The issue with pulling through the rubber on balancers is that you may separate the two...

Not a good idea. You don't want to pull outside of the rubber insert on a balancer.

Yah, I've done this before, (though never on a supra) and it's nothing brain busting, just work and dirt. However I don't have the free time or the place to do the job right now, so.... The transmission has a lot of miles and could probably use a freshening up anyway. Normally I'd be inclined...

I'm thinking you're right. I crawled under there with a stethescope this morning, narrowed the noise down to the front end of the trans. Then took the car for a long run. (It's the wife's car, so I don't drive it much.) Knowing exactly what I was listening for I was able to hear it very...

Buzzing noise from transmission. (99.9% sure it's the trans, I'm going to jack up/crawl under tommorow.) The noise mainly occurs in the first couple of minutes after cold start-up. Sounds like a steady buzzing noise at first, then get's kind of intermitant. (Starts out as ZZZZZZZZZZZZZ, then as...
