Our 86 also had a tricky throttle when I drove it from Houston, took a lot of pedal to get going and slow to come back down . I am just getting to that issue now. Coach has a Williams pedal assembly with a Bendix cruise control /throttle which controls engine throttle lever via a cable . The air cylinder would start moving at 30 psi , then would be reasonably linear up to max travel at 60
Psi . Removed air cylinder /cable assembly and added a few drops of air tool oil and now the cylinder rod starts moving at very low pressure . The quick connect at the end of the cable is frozen in every way, won't pivot . I can source a new cable end and hardware , but the cable is kinked and needs to be replaced . Wondering if anyone can point me in the right direction for the cable ? Otherwise I imagine I will have to go to the Williams actuator. The cruise is not that important to me, but the throttle is aggravating . Sounds like others have similar issues.
Thanks, Chris
