A few months ago my wife freaked out when driving our 1993 SWB - the engine revved between 3,000 - 4,000 RPM with no feet on the pedals. She had to fight the engine with the brakes while the truck was in gear, and after shifting to neutral the engine revved even higher. She stuck her foot behind the accelerator pedal and pulled it toward her, which seemed to correct the problem.
I had a respected indie Rover shop replace the throttle cable. The performance of the truck was different afterwards. You had to depress the accelerator a ways before the throttle engaged. Over a period of weeks I progressively tightened the throttle cable tensioner knob in small increments and this improved the pedal response.
Yesterday I pulled into a gas station and while coasting in at 5-10mph the engine was still above 1,100RPM. I shifted to neutral and it jumped higher, then to park and it revved at 3,000RPM. Pulling back on the accelerator pedal did nothing.
After shutting down the engine I backed off the throttle tensioner knob a little bit. While making the adjustment I actuated the throttle by hand and the spring had resistance, it felt like it returned to its base position okay.
Reducing the tension seemed to help, but now I'm back to a little dead travel in the pedal before the throttle kicks in.
Is there something else I should inspect? I want a responsive pedal but the revving issue is troubling. The truck had been running great for several months and yesterday was the first sign of the revving issue since replacing the throttle cable.
