Engine Performance problem
1994 Mercedes Benz 430e V8 Two Wheel Drive Automatic 106000 miles
about 1/3 of the time when I start my car it runs rough as if the distributor was wet or something, but later it is fine. I have also had this start after driving begins, all of a sudden with no other changes. The power loss is great. The car is still very nice with relatively low miles, can u help?
