horrible engine vibrations.
 

Hi everybody.
(NB: my english isn't very good)

I have just subscribed to mercedesshop forum.
I have some problem on a car i've bought, 300 2.5 DT
250 DT in france. the engine make horrible vibrations,
i've suspected engine mount's, I put new ones in vain.
After that I tried to open a high-pressure between the injection pump and the injector on the fourth injector, the engine didn't change it's behavior. After replacing the five injectors, the problem
is always there.

anywone could help me.
