Google search for "IAC" valve and procedure to clean it. Sure sounds
like that may because cause of your problem.
Sounds like your IAC valve, if you don't want to do the clean-up procedure
mentioned in this group, your other options are to have a fuel induction
service for about $100 with a coupon or replace the whole valve, that'll
require a trip to your dealer and about $400. After that, you'll have to
keep an eye on it, because it tends to return. After a full replacement,
you won't have a problem for a long time...over a year anyway. As cars get
older they run dirtier and this clogs up the valve quicker, that's why
Camrys don't have a problem until the 7 year mark and then most of us have
problems. You can at least put your mind at ease that it isn't serious and
is VERY common.

Thanks for the info I, from reading other threads I kind of figured thats
what it was. I did price out a new one for about $260. from auto zone. I'm
going to replace it the next chance I get just so I don't have to deal with
tearing it apart again for a while.

Try spraying Tri-Flow into the IAC air intake (rectangular opening -
bottom of throttle body, right in frint), with the engine stumbling at
cold idle.
After I replaced the valve, problem returned, but this solved it.
My theory is that there is no lubrication for this valve to rotate -
every time engine goes from cold to warm - and it can stick.
When I took out the old valve, just out of curiosity I pulled it apart,
and there were some wear marks on the surface of the cylinder that
moves to reveal an opening for air flow.
Tri-Flow contains Teflon, and so far, it has continued to work just
fine with a single application to the new valve.
