'99 Firebird (3.8V6) misses and dies at idle

[jescowhite]

I have a 1999 Pontiac Firebird with 107k miles on it. I've had this car since it was new and have been lucky to have had very few problems. However, after the car heats up (after driving for 5-10 minutes), the car will hesitate during acceleration and sometimes die at idle. I have replaced plugs, wires, fuel filter and fuel pump and it is still doing this. I would love some advice from anyone out there who has experienced this or has an idea of what it might be.

I still haven't figured out the problem.

did you try the oxygen sensor if you do not replace that the catalytic converter will get clogged and cause that problem, get both checked and replaced if needed,or have the throttle body cleaned.
