Stuttering

[cereb6]

When I stomp on the accelerator, truck acts like it is missing and stuttering. Doesn't accelerate, bogs down. When I feather the gas, it runs fine and I can slowly get to my desired speed. Any ideas?
Sensor? Thanks.

I would first run a pressure test on the fuel rail to test fuel pressure. Also, throw a couple Chevron Techron fuel system cleaners in the tank. I usually to 3x what they say on the bottle. If that's ok, take out a spark plug and see what it looks like. There's plenty of YouTube videos of how a lean, rich, or well running engine should look. Is it tripping any codes? Could be a clogged cat. Start with those first... dont worry too much about the catalytic converter yet... check those other things first

Mine was doing the same thing after a fresh rebuild. I then got a P0430 code. Catalytic converters under efficiency bank 2. Looking for new OEM cats now

It just magickly stopped. Cranked it the next morning and drove it down the road and nothing. It hasn't done it since. I did buy some injector cleaner and ran it through it. No codes at all. Still driving fine. Bad gas maybe? Software issue? I guess I will wait until it does it again. lol

Maybe some trash in the system or water in fuel and worked its way thru

Nice to hear your truck running good again!

I had this problem but it was every time I drove. Mine was bad O2 sensors.
