91 350 TPI stalling at low RPM when warmed up?
Need some help please! The car runs perfect until I start it up again after it is warmed up. It has an unsteady idle and stalls/ bucks around 1000-1500 rpm. I can floor it and it will get past it and run. It has plenty of power. EGR has been replaced and the fuel filter. What can I troubleshoot for figure this out?

I'm having the same problem. My 92 Z28 actually died this morning. Any ideas??? I'll be working on it later. I'll post my findings after trying some things.

Found this thread and describes my problem exactly. Looks like it is the fuel injectors. I ordered a set today. My car has high mileage anyways so it wont hurt.

GOOD THREAD FIND!!!! I wanna leave work now to go check my injectors!
UPDATE 2/17/2011
I checked all my injectors. Only one of then is within spec. The rest are reading ~8ohms. Looks like its time for injectors. Anyone have ideas on a specific brand, model???
