Rough Idle/Hard Start
I just purchased my 4th MBZ, this time a 1993 300E w/ 52K miles on it, it's very clean.
The car has a rough idle, especially when in reverse gear with the brake on. It has a hard start, especailly when cold. I changed all the plugs, it slightly improved. The suprressor caps for the plugs are different from those found in my 97 E320, but it has the same 104 Engine. No check engine light.
Thanks for your help.
