So you have a check engine light on?
If you didn't, I would say IAF, as you do, I would check the output of the alternator. If it has a problem, and the engine is racing it to put out more voltage....
If you have a CEL there is no way to diagnose it correctly without getting the code(s). Anything else is guessing. You can go to most autoparts stores and they will pull the codes for you free.
