Truck is an 07.5, 157k miles. H&S MiniMaxx tuner, DPF/EGR delete, AFE Stage 2, 5" exhaust with a muffler.
The truck started sporadically running rough the other day, spitting and sputtering hard enough to make the truck jerk. It does it in Neutral under throttle and in gear under throttle.
It sounds like a misfire, but it's almost too random. It will act up for a few minutes, then smooth out, repeating that process.
I'm on half a tank of fuel, so bad fuel doesnt seem likely and the filter was changed 7-8k miles ago. I'm about to use some fuel treatment to rule that out.
Only other thing I've tried is downloading and reinstalling firmware/updates, which didn't help.
It's not throwing codes, fuel line pressure, quantity and timing is all staying constant through the hiccups. Any thoughts?
