HELLO ALL, THIS IS MY FIRST POST TO SITE!

I have a 1998 C 230 with 101, 000 miles on it.

After startup and driving for 5-10 minutes when I drive no problems but when at idle in drive and stopped it will shake for 2 seconds but not turn off. It wont do it after that at all until after cold start. Doesn't matter outside temp. no check engine light. Sometimes rough idle in park. No problems at all accelerating to 100 mph.





WHAT CAUSES THIS. Throtle body what symptoms from this, MASS AIR SENSOR NEEDS cleaning replacing? WHAT symptoms if maf sensor goes out?



SPARK PLUGS CHANGED 7 MONTHS AGO WITH FUEL FILTER.

Ideas would be appreciated!
