Truck Jerking after a stop then lightly pushing the gas pedal

[Jcook]

I’m new to the forum and have 2016 GMC Sierra 4x4 truck. Me question is this what makes my truck jerk forward after a stop and go ( even a rolling stop after acceleration)??????

[richard wysong]

probably the transmission, hows the fluid level?

[Jcook]

The fluid is good, I checked that first thing. Thanks and keep any suggestions coming…

Check for ETC or IAC valve issues. Depends on engine.

Try doing a TMC reset.  Search YouTube for videos on this rest.

Not same thing. Check the electronic throttle control, ETC and IF there is a IAC,  idle air control  module or controller check it, both can affect off idle tip in tip out and stick.

It could be throttle pedal "flexing" causing similar issues. There are a couple threads on this but take a look at this one. Maybe this will help.
