I was trying to adjust my cold start idle and the stinkin' lock nut fell off and is lost, and now the allen wrench-adjusted bolt won't even turn and I think I might have stripped the threads. What do I do? The bitch of it is, the cold idle is now at like 4K, (I adjusted it the wrong way before starting the engine). If I can't get the bolt to turn, am I going to have to get another TB if I ever want the cold start idle to be normal? If so, what TB will fit? Or will I just have to take it apart and see if I can get it back to normal on the inside? Any help would be appreciated.
