My Supra keeps dying on me
 

My 1982 Supra keeps dying on me sometimes after it gets warm, it just shuts off and will not start back until it cools off. I can not figure it out. I have done a comepleat tune up, changed the fuel filter, air filter, water pump, thermostat and had the gas tank sealed. The temperature gauge stays in the middle, it does not seem to be overheating at all. A friend came over and messed with the air meter screw and it did not seem to help. I do not know what to try next????? I took my Supra out for a ride tonight got it up to temp. and every red light i came to it wanted to die, i had to keep it reved up until i got home i took my foot off the gas and it died on its own and again it would not start back for about an hour and a half. Some times it runs just fine, the check engine light does not come on , fuel milage is fine. And i do not know what or how the cold start injector works, common sence tell me it might send gas into the engine when you first crank it over????? I own an 1982,1983 & 1985 SUPRA's. The 1982 is the one i am having problems with the other two I am fixing up a few parts at a time if you know what i mean. I really like these cars, I used to test drive the 1982's & the 1983's at a Toyota dealership along with the other Toyota models that were out at the time when i was a 18. I raced a beat every Corvete i could find.

Sounds like the ISC valve is going out of it..Or possibly the fuel pump is on the way also..These give tell tail sighns at low RPMs mostly..Check those out and let me know..

Had the same problem with my 82 . turned out to be the pick up coil located under the distributer . 1 of the 2 wires had broken and as a result the car would work perfect until it hit a certian temp then the break in the wire would seperate causing loss of spark it was like someone pulled the keys out. I would wait a while and vaarooom back in action again for 20 mins. very frustrating!!!!!!! One wire is red the other white . check both with a meter for resistance but I just pulled on them and i could feel that 1 was clearly broken . $200.00 can from Toyota . Good luck and MKII's rule!!!!!!!!!!!!!!!!!!!
