hey guys i have a 1993 trans am and its running good and then bad all of a sudden. after driving around for a little bit then shutting the car off it wont want to start again for awhile, until the engine is cold i think. it also will do it when im driving down the road then it shuts off all on its own then its back to waiting awhile until it starts again. i've replaced the optispark, coil, and ignition module and it still does the same thing. anyone have any idea on what could be causing this? cause im tired of spending money for no reason.

i had some guy check it for me and he said it wasnt throwing up any codes.

You should check it right after it dies do you know how to pull the codes with a paper clip 93 is the only year 4th Gen you can do it on

Ziegele
