Hi All,
Part 1 - Last week I had some trouble with my 1983 300D, it would start as
usual but run a little rough (popping like it was having trouble getting air).
After a few minutes it would smooth out but run a little hotter than usual. A
few days later the ac compressor started making noise, the clutch stopped
engaging and the air blew warm.
I am in the process of deciding whether to replace the compressor now or next
spring.
Part 2 - Yesterday it took me 10 minutes to start the car, I ran the battery
down and even needed a jump. Black smoke was coming out of the exhaust while I
was chanking the engine. The glow plug light appears normal going out after a
few seconds. Eventually it started , ran rough for a couple of minutes than
ran normal. This morning the same exact issue with extremely hard starting.
Here are my questions:
Could the ac compressor issue be related to the hard starting? I disconnected
the wires to the compressor but I still hear a squeaking noise from it
occasionally. Should I remove the belt from the compressor to lighten the
drag on the engine if the compressor is hanging up? Could that have anything
to do with the hard starting?
If these issues are unrelated any suggestions on troubleshooting would be
greatly appreciated!
Sincerely
Bob
