'95 C280 went in for 30K service. Came back
with a sublime tumble while idling in
drive and neutral. New spark plugs.
Mechanic said he 'scoped' a wire
going bad but did not change the set
until I would tell him when problem got worse.
So, now (1 month later) the engine idles with
a more pronounced single intervaled
I wonder if mechanic may have pulled wire
to a spark plug and damaged wire ?
Benzmac archive states that MBZ plug wire
are good quality and the metal ends can be
changed. I don't feel its right to
spend another $200 for new wire set
I wonder if the spark plug gap is
correct. Could this be the cause?
I want to check it before giving it back to mechanic. It idled fine before
the 30k service and after, it didn't.
p.s. not dealer but indep. MBZ shop
