Just wanna run this by you guys. If cold started, all is well. In fact, this morning I forgot about the issue as I got in an took off. But once warm and restarted, I can stall the car if I wish to just by pressing the accelerator most if not all of the way. It runs like pure crap. Then, as if a switch is flipped, she run just fine. Cherps second in fact (if I really wanna push it).

This is very repeatable. The time from a hot start to "im fine now" is probably less than a minute. Revving the engine slightly helps. (it will not go much past 3k anyway).

I feel its an O2 sensor issue. Or maybe the idle air control valve thing. This was a sudden issue that came up with no warning at all. I have not dived into things yet but I wanted your input incase this is an issue seen before. Then I will go from there.

Thoughts? Any help is appreciated!
