4.2L throttle problem
I have a '98 F-150 w/4.2L engine.The engine rpm's increase then return to normal every 15 seconds or so whether the engine is at operating temperature or not, idleing or at highway speeds.Seems like a sensor doesn't know the engines warmed up.Some days it won't do it at all.Is it the TPS?
