I have a misfire in the car which happens on and off when driving easy. It happens as I start to accelerate from about 1500-1800 rpm. It doesn't happen when driving hard. The maf was changed on the car not that long ago, so I don't think its that. Anyone any ideas what it could be. Maybe I should just clean the MAF? I have scanned the car with vag-com and it doesn't have any faults..
