High Idle

[nikko7mge]

I have a 2005, and I've noticed that my idle is higher than normal when its raining, or has been raining. I can accelerate and let of the gas and I will get a quick jump in RPMs. I've tried the pedal dance sequence to get the idle back down. It worked for a while, but now I'm having the same problem again. What's the problem?

Is it only when your defroster is on? That can effect idle

The defroster has no affect on it. Seems more weather related than anything.
