I recently had this same problem with my Newell. Turned out to be the Air Actuator on the Accelerator Pedal. Yes there is one there, and it has a Plunger in it that will wear and the seal will leak.

The fix was a New Unit, $200.00 at a Truck Parts store and about 2hours of my time. Check yours out. Mine was located at the Top of the Accelerator Pedal.

Good Luck

What year and number is your coach?

The coach with the air throttle is a 74 if I read 2bde’s other posts correctly. Pagosa Larry will have an electronic throttle.

Great video, your a pro! I use an older unit made by Biddle and its been very successful in finding leaks on my coach and others, I call it the cosmos ray gun. Good to know about the air throttle and the year, after your adventure in Alaska I carry a new spare.

Found that leak, a brake line behind the steering wheel. Easily fixed. Thanks
