started doing it about a month ago, havent changed anything.
only does it with the a/c on, surges between about 550 to 950 then onece in a while it will shoot up to 1500 rpm.

after reading some related idle problem posts, I think im going to change out my iac. where do i get one? hows the install? where is it exactly? thanks for any help.

car just has basic bolt ons, 65,000 miles

Never hurts to clean/replace IAC. But I really think you are low on freon which causes a/c to constantly cycle on and off. Have that checked.

Im getting my oil changed, spark plugs, and fuel filter replaced next week. Ill have them check my freon level to. Its not something I can check my self is it?
a/c blows ice cold tho.
Where can I buy a new IAC?

You need to check your r34. My 99 cobra did the same thing until I recharged the a/c. My cobra did it with the a/c and the defrost on.
