Hey all, even though I've been a member for a few years now I haven't really posted a question yet.
My 99 es300 idles loudly at about 1100 rpm as soon as I start the car (not cold, its summer)... it is really noisy and it makes me cringe... however as soon as I put it in reverse it drops to its normal ~600-700 RPM... and it never does it again, even at traffic lights.
So basically the problem is only RIGHT after I start the car and still have it in park.
I've been looking around the site and I'm thinking it could be the throttle body that needs to be cleaned? I'm a complete car noob so I'm not sure if that's right.
If anyone has any suggestions or guesses it would be appreciated.
Thanks!
