Hi all 

So ive got the 1.6t GTC and get a small misfire when accelerating sometimes. Have already replaced the spark plugs and put in a new coil pack (old one showed the usual signs of wear) 

It doesn’t happen all the time, mainly if accelerating in 5th 6th gear on motorways. 

Its been into various garages but none can figure it out. Its under warranty intil June so ideally would like to get it figured out by then. 

I dont get any error messages or warning lights, its also pretty inc
