How To clean out your IACV

IACV = Idle Air Control Valve

Locate your IACV. It looks like this and on D series engines its mounted on the rear of the intake manifold near the throttle body, and on F series engines its mounuted towards the front of the car on the intake manifold near the throttle body.

Remove it, all you need to do is take the 2, 12mm bolts out, disconnect the electrical connection, and your heater lines that run to it. (note put a rag on the heater lines so it doesnt spill everywhere)
Take some brake cleaner or carb cleaner and spray out the screen, which as you can see is very clogged on my 180K+ D15b8.

You can also take off the bottum part and inspect the gasket to make sure its clean and dirt free, and in my case it was

Let it dry, then reconnect your electrical connection, your heater lines, and your bolts and BAM your done.
