rough

My 1997 E320 engine is starting to shake or shudder significantly at low speeds and the car is running incredibly rough, since 3-4 days. The car has had a CEL "camshaft position sensor" error code for over a month now, without any problem. The car has about 150000 miles. The spark plugs...

I have posted about this before but the problem has returned. I have a cold to warm rough idle problem that disappears once the engine is hot. The rough idling feels like it's only running on 4 or 5 pots. Once above 1000 rpm it's smooth running on all 6 and pulls as well as a 300 non turbo will...

Good day, my name is Lucian. This is my first post here, sadly it is of a problematic nature of my car and i seek your opinions and guidance to aid in resolving the issue. I will start with some facts about the automobile. It is a MB 300ce coupe produced in 1990 with a five speed automatic...

Hi All. Dad's been taken gravely ill and I'm running Mum to & from the Hospital in Spain in their 2003 ML270, (95K miles) but it's running rough & I need to do what I can quickly as it's their only car & can't be without it at a garage right now for obvious reasons. Starts OK cold, takes longer...

Hi all, Had the car serviced last week, full oils and filters as I've just bought the car. It was running well previously although the mechanic said all the filters were full of crud and had clearly not been changed recently. However now when I stop the car at a junction it frequently idles...

when I say rough its more a blip now and again when sitting in traffic hot or cold, so far I have fitted ILFR6A X16, 16 X HT Bosch leads, and even changed the inlet gaskets, car has done 60k and at £5 each for the gaskets from merc I would defo recommend changing these, as mine where shot and...

This post is to be added to the pile of 'poor idle' threads that can be found on this forum - perhaps it might help others solve a very common and often an extremely persistent problem with their W124. This post relates to 4 cylinder M111 engines like mine, and the 6 cylinder units built post...

Haven't experienced it myself, but the wife reported problems with the car running smoothly earlier where she said it was "like a manual bouncing off the clutch" edging forward or back at low speed, ie. all jerky. Cleared up after being parked for 45 mins. Does that amount to anything obvious...

Seen a C270CDi I quite like (not the one I asked about the other day) but struggling with a heart or mind decision :confused: Looking for a rough idea of value on my CLK selling privately (or anybody on here interested?) 2000 plate (update model) CLK230K avantgarde with 127K. Engine sweet as a...

Hi guys, my w202 c220 Cdi all of a sudden just started smokin whilst I was driving, smokes a little when idle and exhaust emission smells, has now got a rough idle, when I drove it smokes and i think I can now hear a ticking noise from the engine. It's just white smoke. Any ideas guys, thanks.

my clk w208 230 k seems to not idle propley any ideas why ?:(

Well i just bought a 1997 sl320 that had been sitting for about a month not being used. I know the vehicle ran good before it sat but Now out of the blue It has absolutely no power, in neutral if you ever so gently ease on the accelerator it will rev up but not well it hesitates and breaks up...

Hello all. I have recently changed my spark plugs and inspected the wiring loom and HT leads and all seems well but car still seems to idle rough some days and some days it doesn't. Does anyone know how i will access the throttle body on my C124 to clean it? I will also be changing the fuel...

Hi guys, I have recently purchased an E320 CDi, 2001 with 82k on it. After the 200 mile round trip picking up the car I noticed it felt a little rough on tickover and it sits about 600 rpm at idle. Is this normal idle speed for this engine? It seems a little slow to me? Also on the run...

HI looking for some help with my sl55amg 2004 hot or cold rough when at 1200 to 1800 not coil packs or leads or plugs any more info would be helpful thanks :doh: apart from that go like s--t lol

I have a W203 C220 52 plate CDI when I start it its ok, If I have it stationary and rev it to 1500-1800rpm its starts to shake like its on 3 cylinders. Runs fairly normal once i get past the 1800RPM, once I drop backt to idle/low revs runs rough. If i switch off the engine and restart it goes...

Hi Wonder if anyone could please advise, i have a '99 clk 230, now has 90k miles on clock, bought last year with 56k. when I first start up (starts 1st time every time) there is a roughness/vibration through the car, it's not too drastic, but enough to notice, it doesn't seem to be rpm related...

Driving home about 30 minutes ago I pulled out from the New Forest on to the A35. It has traffic coming up fast at times so a decisive get away to join the road is always best. As I did so the engine warning light came on. I had started the car a few minutes previously and at that time the...

If there are any detailers reading this could you give me a rough price to polish out light scratches and swirls on a 2002 Jeep Grand Cherokee. I only really need the scratches and swirls removed as I'm quite happy to clay, polish and wax it myself afterwards. I just think it's a bit of a waste...

Hi Hope someone can shed some light for me? My C200 estate is occasionally running rough. When it does it feels like its on 3 cylinders (not sure if it is tho) but still runs and changes gear, just slowly and erratically. To solve it, I pull over and switch engine off/on and it's gone. This...
