My 81 300SD is due for some maint. work.

With 315.000 km and no service record (or manual) should I be looking at replacing nozzles?
Lately, after about an hours highway driving, there appears to be some rough idling when pulling to a stop.

Had the valves set when I bought the car
at about 287.000km.

Any input is appreciated.

Enjoying this forum a lot
Cheers

That appears to be about 20K miles... so you are probably due for another valve setting...

and if you will check these sites , plug in your car... you can see if there are known problems and solutions listed in TSBs....

I think there are some specifically idle related,older car fixes listed...
