I have a vw fox 2006 1.2 and have had it for just over 3 months. I have noticed it starts to misfire and the engine loses power sometimes coming to a complete stop after a stall or judder when revs are below 2000. This only happens after a heavy downpour of rain and usually the next day after it has rained when it is humid particularly now in the summer months. I have not been able to find a solution to this and have had fault codes read with intermittent P0302 misfire in cylinder 2 recurring again and again even after all ignition coils replaced with new ones, wires checked and spark plugs replaced to new ones. Does anybody have any similar problems? Or has anyone found a solution?
