It is a 1991 not 2009 Ford Ranger. When the truck is idling with the A/C off, it idles fine, but when the A/C is turned on, it shuts off. The throttle body has been cleaned, MAF sensor, TPC Valve, TPS and ECM has been replaced. When the AC is off sometimes I have to apply more gas for it not to shut off. Another thing, if you disconnect the throttle position sensor, it idles rough and runs horrible, but turning on the AC will not stall the truck.
