How hard is it to change the IAC? Our 99 has been doing this for a long time (sluggish acceleration when cold). No codes, and all tune up items are fresh. Few more miles, however... 153,000.

And you don't always need a part.

Pull the IAC off (2 security torx in my year) and clean it and the passage.. You'll probably find the throttle body could use an extra spray of TB cleaner.

$5 for cleaner... a couple bucks for beer..

yes, as i stated im my initial post, many times a good cleaning is all that things need. its such an easy jub that i would try to clean it, and if it still suffers, then id replace it

I'll pop off the IAC and clean it up. Hopefully that will take care of the issue. The TB is already clean....I just did it 10,000 miles ago when I installed the 4th UIM.

Default Sputtering after cold start

Hello BustOut,
Did you ever figure out what was causing this problem? I think I am having the same issue.
Thanks
Luke

The problem has mysteriously disappeared. I dont want to bring it in to a mechanic unless it starts happening again. I wonder if temperature affects it? It seemed to have stopped when the weather started getting cooler. Anyway, I am waiting for it to start happening again before I bring it in.

Could be on to something here. Let us know if it exhibits those symptoms again with ambient air at cooler temps.
