I have a 1995 C220 saloon. The problem I have is that I had the head re-skimmed about a year ago. Then it started running badly. My local specialist has recently replaced a sensor wire at the back of the engine which has made a huge improvement. I wondered if there is anything else that can be done. I understand that some of these engine cleaning fluid claim to reduce irratic idlling.

It only occurs when staionary, when the car is idling between 500 and 700 rpm, it will suddenly kick up to approx 900 rpm and then drop back down to 400 rpm before settling itself. Beacuase it is an auto it means you have to put yor foot on the brake quite hard when stationary to stop the car lurching forward.

Any suggestions greatly received.

 

YES FIRST OF ALL CHECK THE HIGH TENSION LEADSAND COILS FOR ANY ARCS,ATER THAT CHECK THE THROTTLE HOUSING FOR ANY CARBON BULID UP,REMOVE HOSE CLIP ON THE BIG AIR PIPE PULL OFF AND YOU LL SEE THE THROTTLE WITH CARBON BULIT UP CLEAN CAR WILL RUN SMOOTH AND WIIL BETTER PERFORMACE,, MB TEC PRESENT WITH MB,WITH MB 16 YRS............................NAZ
