my cars idle starts surging when it gets completely warmed up. It will idle so low that it will die sometimes. 500 to 100 rpms. We replaced the tps, but it didnt help. i havnt adjusted it properly yet, but i tried moving it around in about 5 different positions. and it doesnt help. then i tried adjusting it again one day. and then i got a code for the tps.

I tried cleaning my iacv. it wasnt even dirty. I tried adjusting the idle screw, and that didnt help. it runs like crap too, it makes popping noises when i let off the gas under 2000 rpms. I have a check engine light for the intake air temperature sensor. got that replaced. but the check engine light stayed on.

any ideas?
