My 1983 mercedes 300sd wont start and its driving me nuts.  When I turn the
Key I get nothing.  I have replaced the neutral safety switch , the starter
and the battery all in the past year, so I dont think any of those are the
problem.  I tried something my shop teacher once told me ...

Does anyone know whether its ok to run one of those HHO generators on
a diesel engine? My father-in-law is building one for his turbo Saab
car, and swears that they are used in big rigs (diesels) and that they
improve the fuel mileage on them.

I have a 240D that has been sitting in my driveway for 2 years.  It was
having trouble starting when cold.  It got harder and harder to start in
the mornings, then one day it would not start.  So I drove my truck.  Now

A couple of weeks ago there was a reference of where the best places
were to sell a Mercedes car that was directed to classic car buyers.
Could you please let me know what they were?
Thanks

I have installed new ignition switch, blower regulator, and blower
works fine with 12 volts to it.  It works for about a day then stops,
I feel cold air just no blower. any ideas? By the way this is a 93

I have a 300SE 1993 3200cc Petrol and recently when I try to start with the
key it will not activate the starter although the gear lever is in the Park
position, then when it does eventually start It will not let me remove the
key.

the idle is not 'terribly' rough, just not as 'smooth' as it should be.  I note
that the rpm under load (after the car is warm) when idling drops to just above
500 and increases to just short of 700 in park.  I've changed the distributor
and rotor of course, wires appear good ...

anyone there?

I mentioned awhile ago that when the headlights are on and I signal
right, the wipers come on. Funny the first time. I have a used but
tested combo switch. The fantasy of this procedure being as easy as
the R&R in my TD have been dashed. Googling the procedure for getting

I've read all the post on slipping clutches, but mine is not
slipping.  It feels like the clutch is not disengaging.  I cannot get
