gaylemarlowe Report post Posted August 4, 2013 Came back from our trip to Michigan (back to Colorado) in our 99 Monaco Exec we purchased in February this year. Set the coach in the driveway as we were expecting several visitors for our 50th anniversary party and a few wanted to sleep in the coach. After everybody left, attempted to move it to the storage area in the back of our property and now have no throttle. Starts fine, just nothing happens when you step on the accelerator. Cummins 450 engine. What could have happened? Share this post Link to post Share on other sites
desertdeals69 Report post Posted August 4, 2013 Do you get high idle when you hit the resume on the cruise control? Might check the throttle pedal harness plug, may have come loose. Share this post Link to post Share on other sites

dickandlois Report post Posted August 4, 2013 Sounds like the throttle position sensor under the pedal or the wiring in that area. Just wondering if when you came back from your trip, if you vacuumed the coach and just hit or bumped the wiring harness behind the accelerator. Like DD mentioned. If so that is where I would start looking. Could you list the model of your Cummins, Like an ISL or ISM for the group. Thinking you have a harness behind the pedal with 6 wires, 3 for the Accelerator and 3 for the Idle on switch. The idle switch lets the ECM know the peddle is not depressed and signals the engine brake to engage if its turned on. Rich. Share this post Link to post Share on other sites
