Hello,
I am new to this site and from what I've seen, looks pretty COOL.

I have a 1993 500 SL with 60,000 miles on it. At idle when in gear, ie stop light, the car has a intermitten skip or stumble. Once off idle, the car runs fine. I've had it to the dealership here in Atlanta (RBM) and an independent shop, and both of their suggestions was to run fuel injector cleaner through it. This helps a little, but does not cure the problem and once the fuel with the cleaner in it is gone, the car continues to idle rough.

Any sugestions, anyone?

Thank you for your time.
