Engine Performance problem
1996 Mercedes Benz 500sl V8 Two Wheel Drive Automatic 103000 miles
about 2 months ago I started to notice a intermitent hesitation at times when I am driving down the road or starting from a stand still. It does NOT happen all the time. I can drive for 20 miles and have no problem or drive 3 miles and have the problem. It does not backfire but feels like it is not getting gas. I replaced all the plugs and plug seals but still having problems. It happens more when I stomp down on the gas but again not all the time. My father thought it might be the mass air flow but I am seeing no lights on the panel telling me of any problems. When I speak with a mercedes mechanic about the fuel filter, they said they almost never have a problem in that area. How do I tell if it is the fuel pump?
have the same problem?
