In the past few weeks ive been using tesco momentum 99 and the car is running well. Only problem is that the car smokes quite a bit (could be coz its cold at the mo) and the fume smell is unreal. Would this be just the fast its a decat, change of petrol or is there something wrong?

Mine done this, there's a thread somewhere. It was absolutely stinking. Like there was a fuel leak somewhere. I reset throttle parameters and hey presto!
Could just be that. The fuel trim needs resetting.

I've noticed this on mine and I havn't got a decat on. Even after a drive when It's warm you can shut the engine off and it still stinks of fuel? Seems to be inside and outside the car.

About the trims - Won't it just trim up again? It's doing it for a reason so resetting will be a short term thing.
