Can a truck go past 1, 500 rpm?
Can a truck go past 1, 500 rpm? Today my truck left me on the shoulder driving 8-10 MPH. It won't rev past 1,500 and then only at half throttle. When I am running 1,500 rpm and mash it, the engine drops to a constant 1,000 rpm. Why does my diesel engine stop at 2000 rpm? No codes, no lights, just limp it in. Shut the engine off and it would run fine for 3, 4, sometimes 5 miles but would drop rpm to 2000 rpm and into limp mode again. My fuel filter only had 7000 miles on it...
