Truck stalls when slightly touching gas pedal

Oh, come on, it's a BALL!
Sometimes, a failing crank sensor will allow the engine to run, till you ask it to do something...... (like, if you put it in reverse....) Your symptoms don't match up precisely though.... so I would be hesitant to recommend replacement at this point..... Got a scanner that can read live data??

On another note, i still did inspect internally and as i predicted there is oil coated lightly over everything. I didnt see any pooling. Truck is back to normal (seems like ages) but i suppose i need to get that plenum issue taken care of sooner than later?

Sounds like a plan! I have updated results. So my current truck symptoms are that it sometimes stalls/wants to stall if i let off the gas pedal (like going from Reverse to a coast, or Drive to a coast). Is this now back to the crankshaft sensor you mentioned earlier?

So i gotta bring up this thread again, as my original issues are back. Same thing as in my OP: when in reverse or drive, whenever i let off the gas when going between 1-20mph the rpms drop and the truck stalls most of the time (or at the very least the rpms will drop super low until i immediately tap the gas quick to make it idle normal again). As mentioned above, I originally started with the IAC and then i fixed the TPS. The engine ran a bit better after replacing the TPS, but it still sort of had same symptoms. It just got worse over time and now back to where i began. Any help would be appreciated!

Maybe 2 years? Battery is good though; it is fully charged and voltage is great. This specifically isnt battery related. I keep coming back to the IAC theory (even though its new and the throttle body was just cleaned and pcm reset). Its like the IAC isnt working properly..Not sure
