hey guyz, i own a 01 w203 c200k (m111) and i was having jumping idle problems lately, u know the one that rpm dances below 1000 2-3 times when idle while driving. i had the MAF changed but that didnt solve the problem so i proceed cleaning the throttle body today, God it was really dirty ! do u think that was causing the problem ? any experts or anyone having the same problem ?

You should have opened this after you ran the car from cleaning the throttle body... Test it out and see what happens.

i've experienced this on a 05 c230k also, while i was starting up the car it would jump around... is there a DIY thread of Throtle body cleaning?

Thats odd my car idles at 550-600 RPMS

Finally, i got it fixed, it was the throttle body responsible for the jumping after all, its really interesting how dirt can be so harmful such times, if it was possible for M111 to have a problem except this one hahah
