the car is a '89 300E, I am beginning to wonder if I'm also having a problem with my OVP relay. The car idles, in gear, around 500 rpm and in neutral around 700 or 800 rpm. My wife tells me that occasionally she is losing power. Yesterday it happend to me, the engine choked repeatedly but by fiddling the gas pedal it recovered and zoomed away (probably would have done so on it's own anyway). The 'fuel consumption gauge' indicated sky high vacuum while engine had no power. Tried car again this morning when the engine was ice cold and there were no problems (could be fluke I guess). So, I'm guessing engine chokes after it warms up and goes into closed loop mode. The clincher was when my wife tells me that the ABS light came on the other day while driving.... are these symptons beginning to fit those of an OVP relay? IF so, should I simply replace or try to resolder the connections?
cheers, guenter
ps also plan to take apart and clean the ICV this weekend... I'm hoping that spraying WD40 in there should help
