[W126 Coupe] Rubber components --- Was Transmission Problem??

[Andrew Sporner]

I had a similar problem as you mention "shutters and jerks".  Mine had
nothing to do with the transmission though.

I got my car on a rainy day and was driving it home and found I could not
accellerate past 120 KM/h (about 65 Mph).  If I tried, it just vibrated and
acted like it wasn't getting any gas.  The same happened after visits to
the car wash (but only a short time).

Periodically it would turn over (when it was wet out) but not catch.  I went
through distributor caps, etc.  This went on for three years!

Finally last year (I had been to mercedes and they couldn't find it!) I just
decided on a lark to replace the spark plug cables.  The car started
immediately and has never been a problem since.

We found that one if the cables was was arcing against the motor.  They
were the original cables and not very flexible (why Mercedes didn't
find this is \
somewhat of a  mystery to me -- they did replace the coil though).  I guess you
would have had to be looking for this  to find it.  But then again
with a car thats 26
years old--it would have been one of  the first things to look for.

Moral of the story--check the rubber parts!
