Hi again,

A new little issue. My 1980 300SD is a little rough at startup. Starts fine (in all kinds of weather) but the first 30 seconds can have knocks that sound like something is missing. A little rough feeling also.

I can step on the gas (diesel?) pedal to end the problem early or allow the car a minute or so to warm up. Any suggestions as to the problem?

It may help to know that very little has been done to the car over the past few years.

Thanks.

Oh and a huge warning story coming for anyone who needs a mechanic in Vancouver, BC. This is a beauty.
