Well it all started with EML light so i got Wuffer to send me rebiult DKs motor, fixed that light then only six cylinders run off and on while feathering pedal. I think it was about 3years ago i bought them plugs wires of of ebay for a steal of a price like $300 for the set. Well being a daily driver and at 170k miles on me 92 850i those wires went south on me in the cold weather, so i save the bosch wire set that has the plastic covering on them to shield the heat and cold it seems. I put them back on with a new set of plugs and she is back to normal. I do have a problem with windows and wipers not working early in the morning from a first start in the cold but after car is warm we are good. Any help on that would be appreciated.
