thanks guys for the replies,
that darn ovp relay is not in stock in my local mb dealer but they will get it before friday.
any ideas on how to check the starter without taking it out?
what about the flywheel? anything else? why do the cylinders misfire? i use only 93 octane gas and i just changed the spark plugs about 20k miles ago. should i change the plugs again alone with the wires?
