I'm sorry I may sound stupid for asking this, but... What exactly is the IACV, and where is it? Also how do you clean it?

It is the Idle Air Control Valve. Its it located on the passenger side, on the backside of the engine. Your brake booster vacuum hose should be plugged into it. To clean it you can either remove it and dissemble and clean it. Or you can spray manifold cleaner into where the vacuum hose connects. It is a little tricky to keep the car running, have to do it quickly, and has to manifold cleaner. I have heard other cleaners such as carb cleaner and brake cleaner could damage it.
