Subject Vehicle: 1994 C280 Mercedes. (148K Mi.)
My vehicle idles rough at stops and feels like it misses. This continues but reduces up through cruising speed (65) - almost feels like a vacuum leak, although I haven't found any bad tubing. I've replaced plugs, wires and the MAF sensor. A year ago, I had new Coils and injectors installed and at that time the vehicle ran great - smooth. The problem has been with us for about 600 miles. At first I thought it might be from bad gas, but now I've gone through 2 full tanks of gas.
have the same problem?
