Iacs go bad on 8s a lot, test the voltage. Even then it could just have a lot of carbon buildup in it. I've had to pull mine off before and clean it with some seafoam and a toothbrush. If you do need a new iac look for a working used evo 9 one here, the 9s teeth are metal so they don't go bad nearly as often

How could you tell the difference thou if it's the iac over being the iac sensor?

did you ever figure out the problem?
