so i saw a decent sized puddle (maybe 4 inches deep) but i had to go through it, people would have ran into me from behind, so i went through it in neutral, then after, my car revved up to about 3k and then died. i then cranked it, and had to give it some gas to start, but it did start, and i got to a more dry land, and kept revving it, and a crapload of smoke came out the exhaust, and ever since then, my car's been idling like crazy, it fluctuates between 1k and 2k. (ex. vroooom, vrooooom, vroooooom.... lol).

the codes i pulled are
P0507 idle control system - rpm high
P2279 intake air system leak

i've already
-changed my oil, the oil came out smooth, no muddy oil whatsoever.
-checked the idle air control valve, it was clean, only a little black residue in there, which i cleaned out already
-let everything dry overnight, took off the cold air intake and everything
-reset ecu

any other ideas? thanks for your help.

well usually an idle that goes from 1-2 is a vacuum leak, provided you've got a code for it to id start with that.

oh by the way, thanks for your inputs everyone. i fixed the problem. the idle air control valve was dirty as hell, and there was also some water in the sensor that connects to the IACV. i cleaned the IACV with carb cleaner, blow dried it for about 10 minutes, moving the rotating assembly in there the whole time, and i got all the water out of the sensor connecting to the IACV.. continued to put everything back on, and problem solved!

i'd check your valves. if water touched anything really hot, things could have warped
