Had car 6 months now and I have been back at least 5 times, they apologised to me last time I went back as I am there so often. Yesterday the car starts spluttering when I put my foot down and back firing. I am thinking well I have had new coil pack , new spark plugs, just serviced so now what’s up. Light on dash board flashed twice, I look it up when I get home and it’s a fault with exhaust and the miss firing can cause a catalytic converter fail due to miss firing.
I am seriously getting a bit peeved with this car :-(
