something is telling the car to over fuel. as mentioned before it can be temp sens. temp sens would not pull an error, it would show something and car would thing its still cold and give her more fuel than it needs
Should be no leaks as the exhaust is new, But I'll double check anyway.

Actually just realised I'v fitted the Temperature Sensor from another car and it makes no difference.
