Truck jumping at dead stop

[Jeremyleggett07]

Can any one tell me what this maybe? I come to a stop and sitting idling normal but seems like the truck is bouncing up and down. Have not seen any codes, doesn't do it all the time, mostly sporadic. It doesn't do it long either. Any ideas?

ICP sensor out of range, causing spike in IPR duty cycle.

Did you put a tune on your truck? I noticed the same thing after I loaded my extreme street tune. It finally went away, or I don't notice it anymore
