1993 300E 3.2 vibration at idle
After driving my 93 300E 3.2 ten miles or so when I stop at a traffic light I feel vibration coming from the engine. If I turn off the engine and restart the vibration goes away. It feels like if a spark plug is not working. I changed the spark plugs but it did not help.
I also checked all the vacuum hoses, but did not find any problems.
