    Intermittent Misfiring, weather related? Electrical?

    1987 325e. Runs fine in certain climates but in fog or rain shudders and misfires in all gears. After 20-30 minutes of driving usually clears up and runs fine.

    Replaced Spark Plugs
    Replaced Crankshaft position sensors
    Replaced Distributor cap & rotor

    After a week of driving on the new spark plugs, the 3 plugs closest the radiator are indicating rich.

    Other electrical issues/shorts: Active control intermittently indicates brake lights are out, even though they're not. Front left turn signal intermittently works, usually not. Intense audio interference when speakers on in rainy/wet conditions.

    I would start by replacing, cleaning and inspecting the engine ground cable.
