I have a 2004 WRX which is standard exept for a Blitz cat back, it's done 39k
At higher revs and when sitting at motorway speeds then foot to the floor i get what feels like hesitation/ lumpy running
The speed picks up slowly but it feels rough (not quite a misfire)
I had the car serviced (inc plugs) at the weekend but it's still the same
I was running on 95 ron but this last tank i switched to BP Ultimate
Any ideas what it could be or will the dealers be able to diagnose it from their computer?
cheers
