Jerking during acceleration?

[lumberman306]

2020 Ram 1500 Rebel with 155000 kms on 5.7. Recently started to jerk while accelerating. Never had plugs done so have it booked in for that but when I'm in park I can rev the engine and there's no misfire. No codes. New Air filter. Thought it was bad fuel but ran it down half a tank and filled up at different location with premium and no change. Suggestions anyone?

Only happens under load. Once up to highway speed runs normal.

Under load could be spark plug, a coil, or even the boot on the coil. I'm surprised it hasn't set off the check engone light and a code yet.

If I'm light on accelerator no jerking but if I give her gas it will speed up but continue to jerk.

Definitely sounds like a misfire, hook an OBD reader to it and check for a pending trouble code.

Turned out to be a coil.
