This is for a 1992 300D 2.5 turbo.
Can having bad injectors or a bad injection pump cause your car to spit blue smoke and rough idle/shaking?
Theres a lot of blue smoke at start up and at cold start ups, then there is just a tad coming out when idle. I just got my car back from dent wizard who just got the car from the MB dealership.
According to the dent tech, the MB dealership said the cause of the blue smoke and rough idle is due to a bad injector, does that sound right to anyone? I was always under the idea that blue smoke means burning oil, which I do not burn a drop of oil between oil changes. Thanks in advance.
