misfire

The engine loom is back on my 1994 R129, which I am going to collect on Monday, sh1t or bust... The car has been standing for about three months, and now there's a misfire. The seller is getting the spark plugs changed. If that doesn't cure it, it will I think be distributor cap or rotor...

As title ..... I have a w210 240 v6 which has a slight mis-fire on idle and very low revs, I have cleaned the maf sensor with zero result (so .. maybe a faulty maf??) next up will be plugs and plug lead testing along with finding any potential air leaks. What I have also noticed is the gear...

hi all, i have a v reg 230 slk with a bad misfire, it wont even idle sometimes, i have swapped the coils and leads over etc and it always comes back with misfire on cyl 1 and 3, these are the two that are just with leads on , so are these the problem, i cant try a coil pack on either cylinder as...

Hello everyone, I have a 1998 V6 sl320, 120 000 miles and runs like a bird except yesterday, after 100 miles & lunch, started the car and it felt like it was running on just three cylinders. Drove it 25 miles to a garage before switching it off again (just in case it wouldn't start again...)...

I always felt my car had a slight misfire (barely detectable, to the point that i thought i was imagining it) Today though, after a 15mile motorway journey i pulled to a stop, the revs dropped and the car has had a very notable missfire since. I changed the plugs 3 months ago, so (currently i...

Hi, I have a 1990 190e 2.0litre Auto with a misfire. It's only done just over 92,000 miles from new. I've recently put it back on the road having had it on a SORN for 18 months. First time out it ran beautifully for about 20 miles but then started misfiring at low revs. The misfire then...

hello, have a problem with my benz its got a misfire , was intermittent now it wont run hardly at all, changed the plugs, leads, coils and when you unplug the maf it cuts out, so assume that ok, to cap it all the windows have give up the ghost ? it has had a small amount of welding done today ...

Afternoon all, I have had this random engine misfire for a while now and it's been too several indy garages and even main dealer. All they tell me is that it's misfiring on cylinders 1 and 6. They recommend changing plugs, leads and coil pack. I can get the same bloody info off a silly little...

Hi all, My C32 has developed a misfire/rough running in the last few days and it's a bit of a puzzler, as I put the car on to Star at my local dealer (a friend is a tech there) and it showed no misfires at all. I was kind of hoping that it would, so I'd have somewhere to aim for, but it came...

Guys, Has anybody come across on initial start up an engine misfire caused due a weak or undercharged battery? Cheers in advance.

Hi all, having trouble with a class (w169 2005 a150 petrol) stalling at lights and bad misfire . Scanner said map sensor high pressure. New sensor no joy. Cleaned throttle body , new plugs ( one cylinder running rich). Better but not quite right, still not smooth but no engine warning light and...

Hi all, I know there are a lot of threads about misfires in W124s, but I can't find one that quite matches mine. I recently resolved an issue that turned out to be a faulty HT lead only to discover that the engine (E320) will no longer rev beyond 3000rpm. Until that point, it runs smooth...

Hi, looking for some ideas, my W124 230CE (M102.982 I think) has developed what appears to be a misfire but tbh it feels more like the engine is being choked! Not permanent but randomly will just lose power and feels as I say, like in the old days of a manual choke, that it was fully on when...

I bought the old girl (c180k coupe w203) not long ago.. Had few issues.. A couple of days ago I changed my Air Flow sensor for a new Siemens one. Also added 2 starter leads (blockers) as my cam magnets are leaking.. Took it for a spin. All good. No codes. However, I just scanned it and...

Hello, this is my last resort Firstly a bit about the car 2005 cls 55 amg 88k miles Upgrades X pipe Custom manifold Ecu remap Upgraded pulleys So many cell sport cats Problem I've been experiencing a misfire, it comes on at low revs then if I stop and turn it off it goes back to...

I have a 2007 W204 220CDI auto with 170k miles on the clock. It has spent most of its life on motororway journeys, both in England and Europe. It has now developed what I can best describe as a slight "misfire". I realise that deisels can't misfire, but it best describes the feeling it gives, a...

Went on holiday for 10 days and when we came back my C350 CDI had a terrible misfire, felt like it was running on 3 cylinders, luckily it cleared up after about a mile. Is this normal or should I have it looked at? Been running fine ever since, so not sure why this occurred.

Hoping someone can point me in the right direction, I'm stumped now with this. Engine will drop onto three cylinders, no pattern, hot or cold, the only connection is it only happens when you lift off the throttle, then go again (junctions, slip roads etc) Turning it off and back on resets...

Hi have a 2003 Mercedes e270 cdi which is misfiring, a quick check on our scanner shows the following. 2143-4 - Check component Y76y3 (fuel injector cylinder 3). signal line is interrupted. I have replaced the injector and its still the same, checked all the wiring and cant find any issues...

Hi All. Had the 63 for 2 months now and I am convinced that its on 7 cylinders. Drives ok and return 20mpg but when held at 1050 rpm in neutral the engine seems to have a rhythmic judder as though it's on 7 cylinders. Took it back last week but the service guy said if there are no lights...
