My TPS will not stay adjusted, it keeps coming loose. I adjust it as per the instructions on Stinger's site, but it will not last for more than two weeks before it needs to be adjusted again. It does not become loose enough to fall off, but just enough that it comes out of adjustment and will shift with throttle movement or slight pressure from my finger. When adjusting it, I have tried just snugging it up, and also synching it down and regardless it will work its way loose. It has small locking washers on it so I am not sure what else to do to help it stay put. Any suggestions?
