If it was the shafts, bumping the throttle would not ever work to get 
it back down. Something is holding the throttle(s) open. Usually this 
is a broken wire in the cable, intermittently sticking. I would 
lubricate the linkages with silicone spray lube (magical stuff) in 
case that's what's sticking. Failing all else, I would add an extra 
spring to the return setup.
