Hi, looking for some help with regards with a knocking noise coming from my engine. When the car idles, you can physically feel the car 'jumping' on the spot as the engine ticks over. As you apply power the jumping goes away and all seems to be ok.
Starting seems to be fairly ok, although from cold smoke will often blast its way out of the exhaust - and this is also the case when downshifting on the motorway to overtake a trail of smoke will follow...
Not sure about the knocking noise - cant locate where it is coming from. Has anyone else had the same sort of issues?
Thanks for your help.
