Unmodified 2014 Ibiza Cupra with 79k miles.
So about 4 months ago I had my water pump supercharger clutch assembly replaced as it had failed.
Since then I've been having an intermittent misfire on cylinder one.
So far I've replaced all plugs, coils and started using premium fuel and for a while this seemed to do the trick, but this evening on the way home from work it started misfiring and the engine light started flashing and EPC stayed on.
This only tends to happen at motorway cruising speeds when I accelerate in 6th or 7th.
When I'm on a spirited drive down some country lanes this has never happened.
After every journey I check torque and it shows a few misfires on all cylinders which I assumed was within normal tolerances.
Once I restarted the engine the car was fine again.
Any ideas?
Thanks guys!
Need to sort this as my Cupra 300 arrives at the end of the year!
