Hello, My truck has had a quirk since I have owned it. The truck will start up fine, and run for a about 30 seconds, and then begin to sputter and stall sometimes in the morning. This problem is always in the morning, and not weather dependant. If the truck completely dies I have to pump the...

I have tried the cover in both positions forward and back. My boost went from the standard 18 PSI at WOT to over 35PSI in both positions (It pegs my 35PSI gauge, so I don't know exactly how high it is going). I turned the top of the AFC wheel towards the engine, which moved the adjuster towards...

I had the same thing happen to my 97 3500 4X4. It seemed like over night the engine lost most of its power, cruise control could not hold 70 MPH up a decent grade (UNLOADED)!!! The cuplrit turned out to be the AFC Sensing line. This is a plastic hose pipe about 10 inches long, which runs from...
