alright I've been having idle issues. On a normal car the idle shouldnt be stuck. I have a 99 cobra and normal idle is at 800rpms. Sometimes(mostly when the cars nice and warm) itll idle at 1200rpm. But then itll just drop back down to 800 rpm. This is very confusing but im trying my best to explain it.

Basically when im in neutral itll spike up to 1200rpm w/out me doing a damned thing. And then itll drop back down to its normal idle at 800rpms. Dont know what this could be. i thought it might just be something like the throttle being stuck open a little....like its sticking. Anyone that may know of this problem please let me know so it saves me an expensive trip to the mechanic.
