Q: Engine slows, shakes, clicks, and quits - 1993 Mercedes Benz 500 SEL

asked by on September 28, 2016

After having driven a few miles my car slows down, stops, I press on the gas pedal to accelerate, the car starts to shake and then a clicking sound and the engine dies. The battery light comes on and the car will not start for 30-60 minutes. Then it runs fine. I have researched and from what I understand, the problem might be the fuel pump relay. I have been searching for the fuel pump relay seat. I have replaced 8 spark plugs, fuel filter and connector line, air filter, fuel vent valve, charcoal canister, but none of this solved the problem. The engine still quits. An interesting note is that on a hot day when I’m driving on the highway, it does not stall. What is your advice for what I should do to solve my car’s problem?
