Hey guys, I have a 2006 3500, with 22,000 miles on it. I don't run it very often. When I start it up with a little throttle the engine starts running funny. Won't rev up. Sometimes there is smoke. Other times no throttle at all, and the engine runs for a few minutes than dies. Starts up again and runs fine. Any ideas?

smoke points to improper combustion.. perhaps the air filter is clogged (motor compared to cabin of course)... but with only 22k miles, it shouldn't be the air filter unless something is nesting before the air filter some how. my first step would be making sure you have proper air flow.

Possibly a stuck EGR valve? This would affect combustion air.

If it is the EGR valve, can that be cleaned up or does it have to be replaced? :idunno:

You can remove it and soak it in brake parts cleaner, oven cleaner or another of the recommended solvents listed here on the forum.

Are you meaning to say " When I start it up with a little throttle, the engine starts running funny." OR " When I start it up, with a little throttle the engine starts running funny" ?
If the first, it is not meant to be started with any throttle or accelerator pushed while starting, that is only for carbureted gas engines ie 1900-1988.

What color is the smoke? Black, grey blue or grey white? If grey-white, it is because the foot is pressing the accelerator while starting and overspraying the cylinders with too much fuel. To Start vehicles from this century, with your left foot on the brake only.
