Contrary to popular belief now, No UK Police Senator B's were chipped by any Police force in our country.
Doesnt mean it aint chipped.....now tho. lol 
PMSL!!!
Mine too....Wanna Race??

Mayby, while my sensor is out and it has warp speed at the mo.! ha ha, not so much when i replace it

Just found this useful bit of info:
''
Failure Symptoms: *
Excessive fuel consumption, a faulty oxygen sensor can waste 30% of your fuel.
* Driveability problems, such as
engine surging or hesitation. * High hydrocarbon emissions, failing an emissions inspection.
* T
he engine warning light may be on or service flag displayed. * The ecu/computer stores a mixture-related
fault code. * When the oxygen sensor has stopped functioning completely, the catalytic converter may overheat and fail''
Note: the red highlighted parts are my symptoms at the moment.....
only slight hestitation when pulling away, but no real driveability problems as yet. My Warning light goes out after a lil while tho, and the lil 'F' to the left of the clock only pops up for few secs then goes off too..(im only guessing that is the fault code)
