300E engine misfiring in very cold weather
My 1986 300E has always run like a dream until zero temperatures hit this week in Maine. The engine all of a sudden is misfiring on what seems like 2-3 cylinders. I changed the 6 Bosch plugs, but this was not the solution. I removed the distributor cap and all 6 contact points had "green corrosion" on them. I cleaned each contact as best that I could with emery paper, but the problem is really not that much better. Could it be my ignition wires? What is the best way that I can test them on a Sunday ? I am going to order a new rotor and distributor cap on Monday (the old one definitely needs to be replaced). I bought this car with 93K miles and it now has 171K miles. I've got a feeling that the rotor , distributor cap and ignition wires are all original equipment. Could the severe cold weather change have caused the ignition wires to crack? I would appreciate any help and suggestons.
