idle

I have what seems to be a common problem with this car - rough idle. The car is a 1995 W124 E280 estate. M104 engine. The car idles between 600 and 1200 and after 5 minutes it stalls. I’m not very mechanically minded but I would like to try and have a go fixing the problem without replacing...

Hi all, I have a strange rough running problem on my '94 SL500 It started a month or more ago when it started running rough while in a drive through at McDonalds. Almost stalling I had to 'hold' the revs to keep it running. I parked it up waiting for my Big Macs and it wouldn't...

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...

Hi Guys, Just wondering if anyone has any ideas what so ever regarding the car having high revs at normal operating temp? Everything fine whilst cold but as soon as its warm it starts to rev at approx. 1100 - 1200 rpm? Driving me nuts now! The car runs fine other than that :(. I'm thinking of a...

Hi all, I've noticed a slight vibration when the car (W124 320) is idling in Park. It isn't constant and seems to be more apparent when the engine is hot. Whilst not severe it is noticeable inside the car and the doors can be seen to shake slightly when open. Revs do not fluctuate. The...

Hi My E270 CDI 2003 W211 suddenly started to run roughly on idle. The whole car is vibrating. When throtteling the vibrations gradually disappears. It seems not to be any loss of power. One more thing that's strange to me: When I turn the ignition off, the motor stops very suddenly, with a...

As per the title! Can anyone get hold of a smooth idle pulley for me? Part number 112 202 01 19 ? Plus at what price! Usual places like ECP can't get them!

Hi Guys, I've been a happy driver of a E Class Mercedes 60 plate Avantgarde for nearly 11 months now. Bought it a week after passing my driving test and have done over 20,000 miles in it since (there's a baptism for you!). It generally drives well, but am having few issues which are...

My 1995/6 E220 (W124, 111.960) Automatic will not idle. This occurred suddenly and immediately after a car wash. Before the wash it worked fine, after the wash it didn't. She starts, but one needs to keep the accelerator slightly depressed and hold it in a bit to keep it going. With the...

Hi, I bought my W124 E320 last week, and I must say I absolutely love it. However, when I picked the car up it has a slight issue with the revs dropping when putting it into D or R from P. This would sometimes cause the car to stall. That being said, the car runs beautifully without fault and...

Hello Mercedes enthusiasts i hope this finds you well. My 1989 300sl has developed a bewildering display of non/poor running symptoms and having spent the last few days learning/studying all about the ke jetronic system im well informed but still slightly confused as to the exact fault so...

Hello, I have a 1.8 auto 190 93 plate. It's done 104k but has a slight lumpiness on idle and slightly low with fluctuation on start up. Can anyone suggest where to start please, I thought plugs, leads, distributor etc

The part number is 126 540 59 45 on the switch. It has 3 pins not the 2 pin type. It controls idle and full throttle, and is not the one on the throttle linkage which is easily seen this is the throttle over run switch. Thanks for any help here.
