Can someone help me diagnose a a sick Duramax?
Have a 2004 Chev, 1 Ton, with a Duramax. Been running pretty rough of late.
It tends to idle rough, and surges at 55 Mph ( like around 1700-1800 RPM.) Nearly rattles my teeth out with any kind of load, like a steep hill. Power's down, too. When I kick down a gear, seems to run just fine, and also seems to run fine cold, but when the engine warms, starts bucking again.
My first inclination was water in the fuel, but had the filter replaced, and drained the system, little help. I've tried dryers in the fuel, also. I'm in Georgia, so it's hovering 25-50 degrees out these days here, for what it's worth.
I'm beginning to think that it's clogged injectors, but I've only run it 29K mi.
Since I'm not much of a mechanic, thought I'd see if anyone else has had the experience and/or can suggest something I'm considering.
Please, no buy a Ford, or Dodge, or a horse jokes. I'm not a real happy camper on this one.
Thanks,
