Yeah, I know this is a 1st-Gen site but I'm almost desperate! Does anyone have any experience with TPI? In addition to my '68 I also have an '87 IROC, which is almost a Camaro
. A couple of times lately the car has stalled on startup with the a/c on, and the Service Engine light comes on. Trying to restart the engine results in it runs for a few seconds then dies again. I can let it sit for awhile and the ECM will reset itself and the car will run fine. I've had it on a Tech 1 at the dealership and no codes come up. It only has 64,000 miles on it and is a cherry car and optioned to death, so it's worth fixing. I know I'm sitting on a ticking Time Bomb before whatever it is that's causing this stall leaves me stranded somewhere. I'm thinking maybe the Idle Air Control valve, but I know next to nothing about TPI. The car has developed a very slight off-idle hesitation if that helps, idles high (1500 rpm) on startup, and it only does it on an extremely hot day starting the car with the engine cold and then I turn the air on (go figure!
). Any help would be greatly appreciated.
