Re: Dear LS friends, I need your help.
So its not the Stage 4 Cam that you mentioned in post #9? The one you linked to isn't a wild cam at all, its not even past .500" to be ok with stock springs. It shouldn't idle crazy at all, honestly it should be pretty tame.
Sounds to me like there is either a mechanical problem, or the "big tune shop" dropped the ball somewhere. Do you have any more info on the whole "no cam sensor" thing? That's a red flag to me.
