Throttle jumping

At low throttle engine is rapidly jumping or buckiing as if you are rapidly tapping throttle. smoothes out once underway but next time you let off throttle at crest of a grade and start to accelerate it starts bucking again. will do it with no trailer at low throttle like moving around a parking lot

I take it no codes? Sounds like a throttle position sensor issue.

check your wiring...look behind your skinny pedal and see if there is anything out of the ordinary.

Mine has bucked with the camper in tow only while starting off. Have posted about this and no one has a clue. Neither does the dealer. No codes. Only way to stop it is to shift truck to neutral and it will stop. It has done it less than 10 times without warning. I have no idea.
