I believe you are on the right track. The IAC is probably the source of
the problem. I suggest that you buy a repair manual for the vehicle. It
should have the instuctions for removing the IAC and it might even give
instuctions on how to clean and lubricate it and related parts. Some auto
parts stores such as Kragens and Auto Depot have manuals for sale. Barnes
and Noble has some manuals but not a wide selection. A company called
Hayes makes one for every model. You can call Haynes at this number
1-805-498-6703. The one for your car has this code number 42012. If you
can't afford to or don't want to buy a manual--just read it at the store
or Barnes and Noble and place it back on the shelf.
