QuestionI have a 82 380 sl .It is a slug at take off and doesn't seem to have a lot of power.Also, if it sits for a few day's, I have black smoke until warm.This tells me it's running rich,but I'm not well trained with bosch systems or o2 sensors.Are these commom symptoms?The filters are new and plugs are new.Any help on this would be appreciated.
AnswerHow many miles on the car?
Possible issues:
Leaking Cold Start Valve = my first guess would be this...
Leaking Fuel Injectors
Frequency Valve
Fuel Pressure Regulator?
Oxygen Sensor?
Thermo Time Switch
Warm Up Regulator
Water Temp. Sensor
Bad Catalytic Converters
Worn or damaged valve guides
