Could anyone tell me how to remove the plug (spark plug type thing) from the front cat,it has got a wire on it i'm no sure how the wire comes off, not wanting to break anything.Any help would be appreciated.

 

Without having seen a new age exhaust manifold up close, it sounds like an O2 sensor. If so, the sensor will have a six to eight inch wire, with a plug on the end where it connects to the loom. Find plug, disconnect, job done

 

Many thanks will have a look tomorrow.brad

 

greasemonkey is right.

Trace the wire over a cross member near to the gearbox, unplug, hold the zaust section in a vice and deffo use a ring spanner to undo the sensor !

Mine was sooooo tight that I had to heat it up, once warmed through the lamda sensor came out easily.
