Are you sure it's not a cracked exhaust manifold? Did you buy your Civic from the Honda dealer in Scunthorpe? Oh dear if you did.Hi i have had the same problem three times now, twice changed by honda dealers (£530 a go) in for repair on the 9th. with a local garage. to see if they can do better. did you get fumes in cabin? all mine have been No.1 injector
Funny how things are different for people. Their customer service was good for me but they should have never let a car go out in the condition they sold it to me in. They fixed it for me in the end but I doubt very highly I would ever go back to them.Yes it was from a honda agent but all credit du to scunthorpe's dealers it was the Grimsby dealer i had problems with. as i said i will update on progress with local garage later.
