Hello and thanks,
I've been having a problem for about a year or so with my 2000 Chevy Lumina. It stalls out at stop lights or when idling for a period of time when the weather is warm but not in cold weather? It will start right up but I have to give it a little gas some times. I have also noticed on occation that it surges as I'm waiting a stop light.
I replaced the IAC, plugs and wires, fuel filter, air filter so far. It doesn't throw any codes.
I'm planning on replacing the TPS next. What do you think?
Thank you again

See if you're getting too much back pressure from the cat.

Thanks for the reply. Is it possible for a shade tree mechanic such as myself to check the catalytic converter? What is the easyest way? The car doesn't overheat, and the cat isn't "glowing" from overheating. It is something think about though. Thank you.
