rough

Gentlemen, good afternoon from the Bulgarian MB Club. I am posting this topic as it appears quite difficult for me at the moment to identify where the problem might be, therefore seeking your advise. I have a W208 CLK with 111.944 engine (200 Kompressor - 192bhp). The car is running like a...

I don't use my car very often (I've done 110 miles this month) and have just discovered a potential problem. My car (CLK55 AMG 2000) when sitting it traffic for long periods of time, starts to idle roughly then sometimes stalls. It will re-start straight away and be fine. I have narrowed it...

I have a 1991 300TE, which is very clean underneath, is good mechanically and needs just careful maintenance to keep it happy. There is some rust on one of the arches (both on the outer area, which is a surface blemish, and some on the inner arch, which seems a little more severe). There is...

I have a 2006 CLK280 with a 7g auto and the gear change from 2nd to 3rd is very obvious. When slowing down, the same applies, 3rd to 2nd but I get a noticable bump like a brief shove in the rear end. Anyone have experienced similar if so what to be done? Thanks Ian

hello, lately my '82 500 sel seems to run pretty rough until warmed up (amplified by an exhaust blow around the manifold). Seems to clear when it's up to around operating temperature and is significantly worse when the car's been parked up a few nights. It revs nicely when warmed, and pulls...

I am having problems on my e230 1996 auto. Idle rough when engine is cold, more or less ok when heated up when cold the gears are reluctant to change as there is no power the engine will not rev above 3500 rpm, sometime 4 but no more. kickdown is also affected due to the rpm. when idling in...

Hello a friend of mine has the above car and is having a few problems in the morning. When she starts the car in the morning the engine is rough and won't pull. She needs to leave it running for a while to warm up until it's smooth. Also when driving after it's warm the gearbox is very...

Rash decision but decided to buy a 1986 w123 230te that hasn't moved or started for 5 years I know it's gonna bleed me dry but I have always loved them I've managed to get her started but it idles like a pig with a missfire I've changed so far: Plugs Leads Cap & Rotor Compression ok...

I have posted this before, just wonder if someone might have a wee knowledge on it again, I changed the engine and gear box mount as it was time and I was hoping it would solve some of the roughness of the gear box. Thanks to Franey for the mount , good price and fast delivery. About the box...

Hi All I have an intermittent problem with my W208 320 CLK. When at sustained high speeds of 80 or more the car will suddenly start to feel like its not running on all 6 cylinders and loose power. In fact the more I put my foot down the car actually decelerates. Also sometimes when I first...

Hi having probs with engine when idling its very rough but when driving and accelerating everythings fine? Changed leads, plugs, rotar arm, dizzy cap? anything else it could be, also changed the ovp relay. it is a M103 engine 3.0 thanks in advance Owen:confused:

Hi all, My '03 E220 CDi has the following issues. - Long starting - at times idle goes up and down, at times it is fine. - Acceleration is also poor. when I press the accelerator, i have to wait for the car to start moving - on higher revs its fine and reaches the rev limiter easily. - poor...

Hi friends, I had some work done recently the camshaft sensor was replaced as well as a leaky oil gasket which caused the gear shift to go awol. shes now sounding a bit rough/noisy and drives lumpy.. sorry its the best way to describe it. its not the merc it used to be and shes Its...

Hi Folks, I'm new to the club and to merc ownership. I picked up a cheap 1996 C200T auto recently. It was idling a little rough with a slight misfire so I changed the plugs and it's running sweet now. When it was idling rough and stopped in traffic, gearbox in D and foot on the brake, the...

Hi all, As is the norm for my posts, some background followed by a question. You may wish to skip straight to the footer :) Background The hard gear change was once a rare occurrence. Now it is becoming more frequent. My W208 has done 96k and I have no way of knowing whether the ATF has...

Has anyone paid to have all 4 arches done on a w210 E Class? I've just been quoted £390+vat which i think is a bit steep, i don't have much to compare it with at the moment but i'll be getting other quotes over the next few days. Work getting done was all 4 arches, leading bottom edges of...

Am slowly building up a picture of the rough running of my W163 It is dual fuel petrol/lpg Car starts on petrol until ambiant temp ir reached and then it switches automatically to lpg On start up the car idles but when revved or driven it coughs and splutters and the throttle is...

After I washed the engine of my E320 for the first time I have this problem: the engine is sputtering and "lurching", it feels like something is way off balance. The whole car shakes it feels almost like the timing is somehow thrown off, but the engine still runs. It doesn't seem to do it for...

ok folks have changed the MAF and it is still running rough at idle it is hesitant when you try to rev it.....coughing and spluttering before revving and maxing out at 4000 rpm What is next....STAR code threw up a MAF fault but nothing else Fuel filter? or something more sinister?

The car is definitely beginning to run less smoothly when cold. This morning, it was making bits of trim resonate when idling in D which is new, and I'm sure I can now hear the engine when cruising at 70ish on the motorway. My suspicions are: Belt tensioner - I had the belt tensioner shock...
