Does anyone have any tips on how to adjust the throttle linkages on a 300sd? I messed up the tie rod that sets the idle the last time I removed the VC to adjust the valves, I want to bring it back down. While I'm at it, I'm hoping to find out what all the other linkages on the valve cover do and see if I can give the car a little "tune up". The tranny hasn't been shifting quite right after I messed up the idle too.
