I am still having problems with rough running at a "medium" idle. I have
replaced the TPS and the MAP sensor...no trouble code has come back *yet*
(originally, it had a trouble code of 33 - MAP Sensor).
The truck wants to stall when travelling through a parking lot, or creeping
in city traffic after "touching the gas" a little.
I cannot figure out what else it could be, I am at my wits end on this...and
may wind up doing the last thing possible, taking it to a mechanic.
One thing I have thought of - could it possibly be the PCV valve? I had
noticed a considerable amount of oil (residue) through the tube that leads
into the front base of the TBI from the PCV, might this be a culprit? Or
could it even be injectors? That was another thought, just replace both
injectors and hope that clears up the problems...
So many questions, and sooooo much frustration.
