My dad has an '88 IROC 305 TPI. I drive it frequently. It has a habit of stalling when idling and not starting. It has left me stranded in the middle of a busy intersection during rush hour, pretty scary, with no way to start back up. After the car sits for a while (30 mins- 1 hour) it will strt again. Our mechanic replaced the distributor but that hasn't fixed
the problem. I believe the previous owner tried to performance tune the car. It runs excessively rich. Reeks of burnt fuel. It doesn't stall until the engine is pretty warm and the gas expands from the heat. Also when I push the throttle quickly when the engine is cold, it chokes and struggles to run, where if I slowly apply throttle it is fine. My theory is either the mass airflow sensor or the fuel injectors are calibrated to put way too much gas in the engine at once. How would I go about checking/fixing this problem? Also if anyone thinks it is something different let me know
thanks!

I have an 88 Camaro IROC Z with the same problem. i checked the timing, replaced distributor cap and rotor button, put new spark plug and plug wires on it. it was running really good but now i just have to time it in again because i replaced the heads. i hope this gives you a better idea on what could be wrong.

 

So did that fix the stalling? I think the wires are good. Not sure about plugs. Distributor brand new
