My 83 240D (235K) after idling poorly for a month is now running on 3 cylinders.
Before an "Italian Tune-up" would help the problem has continued and was
intermittent until now.
Valves are adjusted, filters 3 months old, primer pump replaced, fuel additives
used. I suspect the fuel injectors or (I hope not) the fuel distributer pump.
Do fuel injectors ever fail completely? is 235K near the limit? Any other
thoughts as to what it could be?
Thank you, (I am new to this list but am from the old diesel MBZ list)
You say the valves are "adjusted." Adjusting valves days or weeks ago
doesn't insure proper operation. You REALLY need to examine the valves
NOW to insure that there is sufficient valve clearance. Any time after
the valves are adjusted, valve adjustment can change - it usually
doesn't happen quickly, but it can.
I don't expect that valves are the major factor though. I think it's
MUCH more likely to be fuel delivery. Probably either an injector or
delivery valve problem. Easiest check is to isolate which cylinder and
exchange THAT injector with another and see if the problem moves with
the injector or remains (suggesting a delivery valve).
