williamcrawford Report post Posted August 17, 2011 I have a new 2010 Fleetwood Discovery with a 350 Cummins, when I start it and go to put it in gear it stalls for at least the first 4 times, am I not letting it idle long enough? Share this post Link to post Share on other sites
wolfe10 Report post Posted August 17, 2011 Welcome to the FMCA Forum. While you want to idle/high idle until air pressure is built before moving, the engine should not die when put in gear. Driving at low speeds/light throttle until coolant operating temperature is reached is fine. Pushing the engine hard before warmed up is not recommended. Is this symptom new, or has it always existed? No problem with clogged fuel filter(s) or air getting into the fuel system? If none of these common causes for any diesel running poorly, suggest taking it to a Cummins dealer. Brett Share this post Link to post Share on other sites
