Ok, I replaced the overvoltage relay, and the car is better overall, but now to start it will start about 400 rpm, then sput and sputter for 15-30 seconds and then start running pretty well. I may have to start it 2-4 times, and if I give it any gas, it dies. Once it starts running well, it goes good. In the last few months, I changed the fuel pump relay, fuel filter, distributor rotor and cap, and the overvoltage relay. Any ideas? Thanks, as I am over 200 miles from a dealer and I don't know anybody around my area that works on Mercedes.
