Having problems with your Ford Ranger ?
I have a 2002 Ford Ranger 3.0L Edge. I had a basic tune up done (spark plugs, MAF sensor, fuel and air filters, plug wires, cleaned IAC sensor, replace a bad PVC elbow to intake, etc.). My truck run better now but sometimes stalls when I come to a complete stop. My truck will sometime stall, I thing , when the engine has warmed up.
The "IAC" is not a sensor. IAC stands for Idle Air Control - it is an electric solenoid. These are not supposed to be "cleaned". If someone cleaned it, that is most likely your problem. You will most likely have to replace the IAC and get the engine to idle correctly so it will not stall at stops. This is a common problem for Ford 3.0L engines even if the IAC has not been cleaned.
I would clean the inside of the intake manifold including the backside of the butterfly valve. Once you have disconnected the air intake tube you can hold the throttle wide open. Spray the inside of the intake and the backside of the butterfly valve with a spray choke cleaner or a special aeresol intake cleaner. If you can reach inside the intake with one of your fingers, try wiping the backside of the butterfly valve with a rag. Reattach the air intake and see what happens. It goes without saying that the engine is not running during this procedure.
