I forget, have you checked the injection pump timing yet. White fuel smelling smoke is usually due to retarded timing. Would also make the car slow, weak and low mileage. Would also be easier to check then the prechamber holes.

(FYI - they come with new seal rings). When we pulled the old injectors out, one of the seal rings had the center section almost punched out, and we've seen this everytime we've pulled injectors out. Very odd. You can feel a relaxing of pressure while torquing them down that I think is telling us that it's punching that center section. The car runs much better. However, it has an uneven idle - at random intervals, between 1 and 15 seconds apart, it will try to rev up for about a 1/4 to 1/2 second. If you start off from a stop slowly, it runs rough (almost like it's still doing those short revs) till about 2000 rpm, then it's rather smooth. It'sstill blowing lots of white smoke that smells like unburnt fuel. If you stomp on it from a stop, it moves out smartly - very nice. If it weren't for the fog bank behind us, I'd be inclined to tell the son - drive it like you stole it! Guess it's time to pull the pre-chambers and inspect/clean all those tiny holes - I think I have a small size root canal reamer that ought to be just right. _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
