Evening all! My 1987 R107 300SL has started to idle all over the place, a common problem with them I believe. I'm guessing it could be the idle control valve, my question is where is this part located on the car and where would be the best place to purchase one if it is? Also, would both...

My w124 200 8 valve auto idles erratically. But there is also a clicking noise from the area under the bonnet near the servo? The idle is normal for a while then the revs rise and fall to the point it may stall. When the revs rise they go to about 1300. The car is well serviced and looked after...

Morning chaps, Having a bit of a problem with my C200 Sport. The car will start fine for days on end, then suddenly just will not start. It will turn over but just not catch. Try again ten minutes later and the car starts fine. I've heard about CPS replacement, but are the symptoms...

Hello all im new to the world of Mercedes only had my car 4 weeks but it seems to have a slight problem. The tickover is really erratic the rev counter kind of pulses and you can feel the car pull almost as if it was in drive and you were blipping the throttle, there are no engine management...

It seems like it's the season for auto-trans problems. After many miles of faultless service my 1998 E300TD is now sticking in various ratios ... Usually when warmed up ... sometimes it's 2nd. Most often it appears to be 3rd. Once it's started, it won't change out of this. Putting the selector...

Hi All, My 1995 SL500 has an erratic idle. It generally only happens once the engine has warmed up and is as if it is hunting. It is rather off putting because when i come to a standstill it feels as through the engine will stall. I have had the throttle actuator refurbished, and the wiring loom...

Hi. Need some advice.... I have a 1998 C200 W202 which idles erratically between around 500 and 1500 rpm on a cold start. Also the engine seems to 'kick' when driving and occasionally 'pops' which i guess is a backfire. The problem clears after a few minutes once the engine warms up. I have...
