JimF,

I am trying to track down a rough cold idle problem in my '93 400E. I've replaced the rotors and caps and fuel pressure regulator. I am trying to evaluate the ECT sensor. Your post says to test adjacent terminals. When I did, they all showed infinite ohms, but if I test terminals OPPOSITE each other, the readings seem to be about what I expect (216 ohms at 80 degrees).

Am I doing it right?

Also, where in the MB CD-ROMs is this info? I can't find it . . .
