When my truck is left sitting while idling, the idle will begin to lope and is powerful enough to shake the whole truck when the engine gets warm.
I don't have a tachometer connected to the truck right at the moment, so I have no clue what my RPM is when this is happening. I cleaned out my IAC, but the plastic inside is rotten. I cleaned out my MAF sensor (which is from a 2.9L, comes stock with a smaller intake hose). I also replaced my throttle positioning sensor that solved a different problem. I have not yet replaced O2 sensors.
