Slight misfire just got worse
For the last month, my 185 D5 would occasionally produce a slight misfire while driving, usually after turning a sharp corner or a roundabout, after a second or two it would disappear.
Two days ago I replaced my clutch, DMF and rear main seal, and now it is much, much worse. Once up to motorway speeds it drives well, however at low speeds the car is misfiring frequently, and occasionally a large bump or corner will cause it to lose all power and cut out once you dip the clutch pedal. So far I have concluded that it is most likely to cut out when the engine is cold.
These are the parts I disturbed when doing the clutch that may be relevant to this new fault:-
- Control unit atop the airbox & the two looms going to it
- Air mass meter & airbox assembly
- All intercooler hoses
- Vacuum lines & both vacuum engine mounts
- The plastic pipework going to the DPF pressure sensor
I think it's worth mentioning that during the clutch job I noticed that all 5 engine mounts were in very poor condition, and there is a slight boost leak coming from the turbo resonator elbow, which I am awaiting a new part for.
No EML present.
