I'm Adam I just made what seems to be a HUGE mistake in trading my perfect running boat for a 96 E320. I got it on trade as I was told that the throttle body needed replaced. I replaced it with 3 different ones and its still JUNK. The car will not do any more than Idle no throttle response at all. What else could be wrong with this? and does anyone know where i can find a diagram on vaccum lines one is off and i cant find where it goes. please help if you can.
