A little new here, I just purchased a 1991 formula firebird 305, my buddy just pruchased a 1991 GTA.
We made the switch from Gti vr6?s and honda preludes and we must appologize for straying from american muscle, i have no idea what we where thinking.
My 305 tbi runs great, and is in great shape, his GTA is ablsolutly perfect no rust or rot 305 TPI.
Unfortunately his TPI engine runs for 15 mins the stops when it gets warm, then its hard to start untill the car cools down. He spent a tonne of money trying to fix problem and is getting very discuraged.
He replaced, ignition coil, Water temp sensor, added a hypertech chip to manage fuel better, just throwing money at it and nobody can come close to answering the problem.
The mechanic seems to think it is some sort of injector signal or distributor signal.
ANY IDEAS? (my friend and I don?t hang with D-trump if you know what i mean, we have to stop throwing money at it.)
Thanks guys!
