does anyone have or know where i can find a tutorial on how to adjust the throttle linkage...i have an 81 300d and this morning when i went to drive it i got no response from the pedal, i checked it out and when i manually pull the throttle at the engine everything goes fine, but when i push on the pedal virtually nothin, so somehow the mechanical part of the throttle linkage is out of whack...my haynes book is pretty vague and i was wanting to get a bit more information..
