Just an update on our coach issue of sticking open air throttle, and engine shut down switch failure at the same time. A perfect storm .  Bus Grease Monkey of Centerville Tennessee came to our rescue. When we were having these problems , we were already  in route for a long standing ( 4 months) service appointment at the Bus Grease Monkey garage . The following day, Bus Grease Monkey sent his service truck 240 miles  to our campground, freed up the linkage on the throttle, determined that the shut down switch itself had also failed, and then followed us the 240 miles back to the shop. At this point it looks like failure to lubricate pivot points on the throttle assembly, ( that one is on me) and a weak return spring , and worn and binding linkage were the culprits, giving us idle rpms of 800 up to 2000 rpm. Because of these issues, even the Jake brake couldn't activate , making things a little more dicey.
Day 1 at Bus Grease  Monkey Garage. We are living in our coach, inside one of two enclosed service bays, 30 amps provided. Life is good.. 9am start time, and these guys move at a rapid pace. It appears they service only two coaches at a time, so today is all about us . I will continue our saga on another thread, Thank you for all your advice Gurus. This is an amazing forum.
