I had the injectors on my 1987 300SDL replaced in July, with rebuilt Bosch units. I experienced a rough idle on cold startup which, now that temperatures has dropped with the onset of winter, has become progressively worse. My mechanic has suggetsed that it might be the glow plugs or something related to the glow plugs, but this problem arouse immidiately after the injectors were replaced.
Does anyone have an "informed" opinion about rebuilt vs. new injectors? If so, I would like to hear it.
