I don't know what you mean by pull out but have you looked at the easy stuff.

How many miles on the spark plugs, spark plug wires, cracked or defective coils, water in the fuel?

Check engine light on?

Did it do it just once or all the time?

How long has it been doing it?

The IAC was new to me too. It is an aluminum cylinder about 1.5" in diameter and about 3" long and is just behind the throttle plate on the intake manifold. It gets carboned up and can cause rough idle or the engine to die when you start to take off at a stop. You can clean it yourself if your mechanically inclined. A shop can do it for you. If that don't work you will have to replace it.

How long has it been since the spark plugs were changed? Check for bad plugs or plug wires or vacuum leak first. There are several things that can cause rough idle but it does sound like the IAC valve.

I just cleaned the IAC on my 2003 Ranger and it is right on top of the maniflod just behind the throttle body assy. It was a little carboned up and easy to clean.

This is what the IAC valve looks like:




Carb cleaner works good to clean the IAC valve.
