On a cold start (first thing in the morning or after the car has been sitting for a while) the start up/idle is perfect. If the engine is warm or hot when started it will sometimes idle for a second then stall out. Does anyone have any ideas, everything else is good, vacuum/boost/etc..

how many miles on the car?? How about the engine?? rebuilt?? How long was it since spark plug change?? How about the wires??
FYI and for others.. Please do your basic maintenance on your car then post your problems. Most of the issues I've seen in person were mainly maintenance related. ie, changing your sparks, wires, checking check valves, vac lines, fuel filter, etc etc..

The engine was rebuilt by KD rotary about 25,000 mi ago. It has never given me any problems. I have kept up on regular maintenance also. I thought the issue maybe the spark plugs, which were replaced 10,000 mi ago, I'm not sure about the wires, I'm guessing they were put on with the new engine, but not sure.

in my opinion, go ahead and change out the sparks first then the wires. I replace my plugs 3-5k miles. After that if you still experience the problem, change out the wires also. Wires are pretty cheap ($30-$50).

Thanks for your help, I have noticed you have replied to some of my posts before. I will take your advice and swap the plugs later this month.

I have a reman in my car with about 20k on it now. The engine was replaced by the guy that had the car before me. I had to replace the wires about 6 months ago due to bad ignition breakup at higher rpms. So I wouldn't assume they put new wires in with the engine.

True, if changing the plugs doesn't work, I will do the wires too. The ones I have on now are Magnecore 10mm, I assume these are good, does anyone know anything about ULTRA wires from Racing Beat?

Are you running any amps, high boost, or aftermarket ecu?
If not, I would go with stock wires (NGK). also, I've heard awhile back the Magnacore sometime have problem popping out.. but that was few years ago.

All I have is a downpipe, KN drop in filter. Why are the NGK's better if you are running stock boost, etc..
