Just got my haynes manual now i can be more specific.

My 2002 ES300 started to idle high on first start. about 1200-1400 rpm. i had read that it may help if i spray throttle cleaner into the butterfly valve of the throttle body. after i did that the idle went up to 1800-2000 rpm at start up and then eventually slows back to the original high idle of 1200-1400. i have read that some people here have had good results cleaning the IAVC. i can not find any info about the IAVC in the haynes manual other than a brief mention and no info on where it is or how to remove it.

did you try to clean outside of TB where cable drive the TBplate?

idle should be 700-800 rpm

No I haven't, should I ? what should I use ? degreaser and a rag ?

about 50 deg F outside, engine is cold, and RPM should be 800 ? thanks that was helpfull... i knew 1400 wasn't right... .

I have 351,000 miles and never opened IACV, when I clean TB, I spray lots TB cleaner in IACV hole.

Hope that helps.

Camlex, thanks, I will be trying that this weekend. I'll post results...

By the way, 351,000 miles ? can I ask what year and make that is ? just curious
