Its almost like power gets cut off to the motor. But it stops when the rpms get low. Theres a big diffrence between just letting off tge gas a when it does this

thanks man. Do you think theres a way to controll it better? Like on a toggle switch or something?That is called DFCO, or Deceleration Fuel Cut-Off - essentially works similar to an engine brake, but what it actually does is retards timing down to -5 degrees while supplying the engine with minimal fuel. It's something you can mess with in the PCM tune.. Great for coasting to a stop, and uses a lot less fuel than if it weren't in effect. Perfectly normal tho
Sounds like two separate problems; sputtering and dying and the gas pedal depressing on it's own, is it?Okay this is crazy just started happening this evening my truck is sputtering and dying when it has low rpms while I'm driving it. Seems to be doing ok when I accelerate and get it past 30 mph.... But when im braking at a stop light or whatever , the gas pedal is moving on it's own trying to accelerate. Any ideas anybody? 98 k1500 5.7l

Hey guys, new here hoping to get pointed in the right direction. I have a 94' k1500 with 100k on the dash. Months ago I had a couple of very minor misfires and sputtering while on the road, nothing major. Well, I just completed a cross country trip in the truck and the misfire came back with a vengeance. Got to the point where it was almost undriveable. It misfired so bad it blew open my muffler. I got it home, replaced the MAP sensor, coolant temp sensor, timing chain (which did have quite a bit of slack in it), new distributor, cap rotor and module, fuel sending unit and fuel filter. STILL misfires.... The only thing I can think of now is a burnt valve maybe? The truck idles beautifully, once I put it under a load (if i have it in 3rd or 4th and whack it) it misfires/pops, sputters.
Haven't checked compression yet, that is my next step but... for the love of god is there anyone with a suggestion out there?
