rough

Hi guys This just may be a characteristic of an 'old' car, but I have noticed a pattern that if it is raining/has rained my car will start like it is running on 3 cylinders. Turn it off/on and back to normal with a slight lumpy idle. Today with it being dry it starts and idle almost...

Hi all, I hope everyone is well. I noticed today with the seats out the boot vibrates a lot when I go over the slightest bump. I loaded the car up on the return journey, so there was more weight and the vibrations were a little less. Firstly could there be a faulty catch on the boot...

Hi guys, I am a newbie here. I am having a w211 e320 petrol my2003 which has done about 66k miles. Recently, the car is very rough (heavy vibration) when the engine is at about 1500 rpm when cold. There is no warning light - the dash board is indicating that everything is normal. However...

OK, so my idle is still off, when car is cold its perfect, as it warms up it gets a bit lumpy - mostly smooth with a slight miss, also when re-starting car when warm revs fluctuate quite badly for a couple of minutes before settling back to the almost smooth but slight misfire every few seconds...

Recently my clk500 has started chugging whilst accelerating between 60-120 (I know I shouldn't be driving this fast but!!!) the best way I can describe it is like when your ridding a bike and the chain slips! There is also a rubbing/grinding sound/feeling coming from the rear wheel area! I...

Hi, im after a little advice on my issue. It runs beautifully when cold, and when warm, it runs to 90 degrees and stays there comfortably. But after a long-ish journey I start to get some weirdness.. First issue I get is the idle starts to rise, it goes to 1500-2000 ish. This can be remedied...

Hi and a belated happy new year to you. Have a problem which baffles me. When the engine idles sometimes it´s as smooth as silk the next it seems as though it´s running on 5 or even 4. It is fine as soon as the revs increase and driving the car normally is ok as well, no problems under load...

Hi My mane is Glen and I live in Merstham in Surrey. This is my 1st post. My ex wife has an E200 auto estate of 1999 vintage has been running fine since she bought ir 6 months or so ago. Recently though is has been playing up every now and then, but now it's undriveable. It starts OK, but...

Hi folks, Just had a new experience with my C63 today. Had been sitting in the drive for past 4 days in the freezing weather and when I started it up today the idle was a bit rough to begin. Fine a couple of mins later and thereafter. Looking for experiences of other C63 owners here, is...

Hi The C180' (2003) I have is giving missfire codes on cylinders 1, 2, and 4 along with mixture too rich ??? In general the Car runs OK when moving, but idles roughly from time to time hence the errors codes. I have replaced the spark plugs as an obvious first step with no improvement...

my car - sl320 R1290642F177672 Gearbox 722.6 Engine M112943 I have a constant rough idle whether in P, R or N with a bit of surging when aircon is on or steering wheel in motion, i get a light massage felt through my seat when stopped in traffic - i am very sick of it work that has been done -...

Hi I have a W202 1997 C240, Sometimes when trying to over take the power dies and it coughs, was thinking of a new fuel filter to start.....Just dont know where it is?? Or is this a common fault with something else it has 75k miles part mb history and part local garage from previous owner...

Hi all, I have a 53 plate C180K and a few weeks ago the engine started to rough idle at tickover when warm. I have changed the plugs but it seems to be getting worse. The car runs fine in normal driving but when at standstill after 10-15 seconds it becomes rough. On my way home last night I put...

Afternoon, Recently purchased a C180 (w203) 2.0 Auto and on startup it is rough and lumpy, Sounds like the manifold or exhaust is blowing, I have to run it at 1500rpm for approx 20 seconds when cold, then if i release the accelerator after the 20 seconds or so it will run quiet and normal. Im...

Hi all, I have my W124 for 7 years now,really happy miles (apart from changing the wiring harness :wallbash:),I got used to every thing in it. Few days ago I went with a friend to see another W124 for sale,I drove it and I discovered that the transmission shifting is very very smooth(you...

Hi all, Can anyone suggest a possible reason for the following antics being exhibited by my 1995 E230 (W210)? At the point where the engine reaches 'normal' operating temperature, the engine surges whilst driving. If I am sitting in a queue of traffic (in gear) the engine speed seems to drop and...

hi, my 200 has a problem which i thought would go away with the replacement of the fuel filter but hasnt. on a cold start, it takes a good few cranks to get it going, and will cough and fart until it eventually catches. then when it does go it will idle, but as soon as you put your foot on...

Hi all. My beloved C250D 1995, which has done 92k miles has always run a little rough between 2 and 300rpm. It has recently got much worse and barely runs at those revs. It misfires irregularly very badly and poors smoke out. At idle and other revs and even on full accelaration, it behaves...
