I cleaned the engine the other day on my C220 W202 1994, sprayed some water on the engine while it was running, it started hunting, when i finished i switched the engine off, dried everything out, blew all visible connections with compressed air including the HT leads and suppressors, it...

Hi I've got another little problem with my ml270 which is hard to explain. The engine idles rough when in Drive but stopped like waiting at a junction, it's like it needs to get going. When braking it also seems to struggle like it's got warped discs. It brakes like I'm pressing the pedal on...

Hi I went to view this MERCEDES-BENZ E CLASS 3.0 E350 CDI BlueEFFICIENCY Avantgarde 7G-Tronic 5dr Estate for sale in Stockport | Auto Trader today with the intention of making an offer for a straight sale. Everything was in order until the engine was started. It started and idled fine for circa...

Hi, I have a W211 E320 CDI which has just failed it's MOT on emissions. The car passed the smoke test with a reading of 0.02 when the limit was 1.50 but the tester said it had failed due to the excessive visible amount of smoke and stopped the test at that point. I was unaware the car was...

Hi Guys, I've got an issue with my Merc 1996 w210 e230 petrol. When it starts up from cold the idle is lumpy until it warms up after a few minutes, then runs fine. Acceleration is flat and slow, it has only been driven in town, but on Friday I gave it a good run on the motorway and now...

Hello all, My grandfathers car is suffering from an idle control problem. I came about when the fuel pump went and for some reason the mechanic decided to clean the TB. from this the idle problems started. This car does have a sensor attached to the throttle body on the far side. It's also has...

So, I've been fixing up a w203 coupe that had various issues. When I drove it onto my drive 6 months ago the engine purred sweetly and the gearbox seemed nice enough. At various points over the last 6 months I've started the car, had the battery on and off, recharged the battery after it drained...

When I move off from standing start the engine hesitates a little before accelerating? My engine idle speed is a 500rpm. I am wondering if it is to low and that is why the engine sounds like it is going to stall when I press the pedal

When I pull away from a standing start the engine hesitates a little before accelerating.I am wondering if my idle rpm is to low.I it just a touch over 500rpm

Hi everyone, Just wanted to pick your brains on this one..I purchased a w140 s320 limo business edition in august. Great car, which I purchased from a relative. As the owner has passed away, the car was parked up for about 9 months. When I got the car the engine was running rich, black...

Hi all, Every so often when coming to a stop the idle starts to fluctuate, be rough etc. from what I understand this is most likely to be the MAF sensor. As soon as throttle is applied it clears up and runs perfectly. If it's starting to go then is it a straight swap or will it need to be...

Hello . I have a W211 E270 2003 and when temperatures are negative as soon as I start the car i have a fluctuation at idle for about 10 seconds. It`s not a big fluctuation.... between 800 and 820 rpm after which it stabilizes at 800 and when it warms fixed drops to 780 . Do you think it`s a...

========================== Cross-post – apologies if I’m bending the rules here – but I’m not really sure that the previous location was entirely appropriate - asking EuroCarParts for advice on sourcing a TB from one of their competitors http://www.mbclub.co.uk/forums/2015220-post933.html...

Hi. I have a 2001 Merc Vito 110 CDI which keeps going into idle mode when I get into 4th gear. It just revs to 3000 then doesn't give anymore power. I have changed 2 of the 3 boost pressure sensors ( one at the top of the engine and one underneath. The last one is at the wheel arch from what...

What is the 'official' idle speed for E350 CDI W212 please, and what if anything would cause it to drop? My motor seems suddenly to be a bit jerky in slow traffic, the braking effect of taking my foot off the accelerator being quite harsh. The rpm on idle is a cat's hair above 1000 rpm, but...

I have a 1990 W124 300TE which has developed an idle speed issue over the last few days. When I start it from cold it idles at around 1500rpm instead of the usual 800-900rpm. I put this down to the weather going colder and it having to use choke but even once the engine is warm, it still idles...

Hi All my sprinter 313CDI died the other day while driving. replaced filter. primed up ok but wouldn't start. gave her a tow. she started. we could rev her up and down all day but when it came to getting her to idle, she threw on the EDC light and cut out. reset the key and she started...

Hi All, My 350SL 1979 model suddenly wouldnt start. So my local garage changed the fuel pump and had some cleaning done to the fuel distributor. Now the car starts but does not want to idle. Any suggestions on what could be the problem?

Just brought the 124 back from Italy. Ran perfectly all the way. 1,000 miles with just stops for fuel. However now when hot the idle hunts from about 600-1000rpm but not all the time. Found a previous thread suggesting the egr valve but not sure where to find this or if it has one. In the past 4...
