I have just performed an ecu reset,which has brought up a fault with the oxygen sensor,my car is a 1998 uk turbo,fitted with an itg panel filter,and a haywood & scott full de-catted system from the turbo back,would this oxygen sensor fault be normal with the above mods,or is this something i need to worry about ?.Any advice would be very much apreciated

It's not uncommon for the Sensor to fail shortly after being moved into another downpipe, should be fine to use for a short time, but get a new one fitted when you can!
