Apparently ur IAC valve is dirty , I had the same problem with my ES 300 97 , after cleaning the IAC valves it was fixed. Search the forum for IAC valve

Thanks Rizwan, I'm going to give that a try this weekend.

The A/C was off, I decelerate normal just like i stop at any redlight, I was in DRIVE mode, It happend when I'm at full stop waiting for greenlight. Thanks for all your reply.
