C280 has me by the seat of pants...

[unkl300d]

1995 C280. Had my 30K service done by
ind. MBZ. shop month ago. Got it back with
background rumble in idle. Got it back again
today with new spark plug wires(no chg.) because an end cap was apparently broken
(mechanic probably broke it-they r having problemos at shop)
The issue is that the car has less violent
'rumble but after it is warmed up and in park or neutral, I can feel tremors to the seat of my pants in driver's seat. Like a heart arrythmia. Tach needle just moves up a hair.
It did not have this behavior before
the 30K service, so I wonder whether this
is normal idling or whether I should suspect the new plugs (gaps or failure) ?
I feel like taking it to the dealer and giving the bill to my mechanic.
Please help!
Thanks

Take it back and demand that they correct there mistake. If it was not like that when you dropped the car off, then it is there fault.

If they are having problems in the first place, than this will be nothing new to them. Also, I suggest you find another shop in your area for future repairs/services, run a search in the "Good MB Shops" section for a possible lead.

Good Luck.

Thanks ROAS, yes I took it back today.
It's an ODDYSEY and my name ain't
HOMER (not the car and not simpson!).
I left out all the betwixing
comings and goings of this drawn out event. No need to spread aargh.
Yeah I'll definitely drive to another city
to get good service.
Hope I get it back without any more domino effects.

Thanks Carlson_190E,
I will call ********

a slight surge after the stronger
cylinder miss.

Thanks again.
