lumpy

Hi folks, I have a Mercedes E280 CDI (2006) and it is very 'jerky' when cold between 1st & 3rd (I think), there are suggestions this is normal when cold and starting off in slow moving traffic, is this true?

My car has been running lumpy when stationary or at crawling speed once warmed up - can anybody advise what the likely culprit is? Thanks, Dan

Hi all, I have a W124 prefacelift 230E M102 engine auto.. I was just wondering if it was possible to modify anything so I could get a lumpy idle, sort of like a 500E with exhaust upgrade or american muscle car idle sound..? I know those cars have V8 engines and have nothing to do with my car...

Hi Peeps, I have a C180k Coupe (2003, 91,000 miles) which dosent idle very well. Once the car has warmed up when you sit at a set of lights the needle moves up to about 1800rpm then drops to about 800rpm and keeps doin it until you pull off. The engine sounds a bit noisy so I dunno if...

I get a diesel smell in the cab intermittantly on start up, also a lumpy idle, wondered if I had a leaky injector ? Maybe the lumpy idle is the heater booster? Also if I was renewing the copper injector washers would this be a good time to renew the thermostat as I only get to 50d, 70d if I am...

For a while now, my W202 has has a slightly lumpy acceleration. This happens only at low revs and usually is noticeable in low gears. If I put it into first, and pull away applying a lot of clutch down, it's fairly smooth. That said, if I release the clutch, it's quite lumpy... My...

Hi A few months ago I bought my first ever MB, 2001 c240 Automatic. Lovley car, but its developed a problem that has thrown the local garage... About 2 months ago the car started to missfire, loose power when trying to accellerate (or reving the engine in park/neutral), struggles up hills, and...

First, do these things ever run right ? Last three days after starting fine the idle is going up down for a bout five seconds then settles. Driving is normal. If i turn the engine off and restart immediately it still does it. After three days of this. Now a dirty scummy smell has started, comes...

I managed fix my lump running problem with a replacement injector but have since noticed two things. The first cold start in the morning is lumpy/shaking until I rev it or drive off with it and as soon as my temp goes above 80 degrees it feels slightly lumpy, like the fuelling is slightly out...

Hi All, I recently aquired one of these with 86k on it and a very clean example. Unfortunately I have ended up spending on it none stop and now can't solve one problem. Firslty, the car wouldn't rev above 3000. I overhauled the intake manifold, cleaned up the flaps and egr while I was at it...

In the past three days, my otherwise perfect C240 (2.4) has developed a bit of an intermittent misfire complete with lumpy idle. The fault just occured, no hints or signs. I first noticed it when there was a momentary loss in power when pressing the loud pedal followed by one or two small...

Hi all. I have a 4 speed auto c180. Its done 130k. All changes are smooth apart from 2nd to 3rd which sort of lumps in. Nothing drastic but far from smooth. Is this just a worn gearbox or can I improve things by giving the gearbox a good service with new fluid and filter etc. Thanks John
