I have only a couple of things left to fix on my 89 W126 3.0. Inconsistent ( surging) idle is one of them.. The others are motor mounts, and both muflers..

Guys, I have a couple of questions I hope you can answer..

When I adjust the voltage to .7V between pins one and two, do I accomplish this by adjustment of the trim pot screw, or by swiveling the unit on its' axis????

Does anyone know if the part # on mine will be the same???

Steve, If I read correctly.. You simply removed the old unit, adjusted the trim pot screw to the same value, and re-installed in the exact same location.. With good results.. Correct????

THanks,
Jay
