You mean the lambda sensor? Don't cut it mate you can just remove it from the decat

oxygen sensor
noooooooooooooooooooooo!
that's the o2 sensor. you will need that mate. you should be able to unbolt it from the decat. either than or remove the plug on the other end of the wire..

exhaust mani bolts: how to
get lots of penetrating oil (wd40) and be generous with it. let is soak for a couple of hours then whip out your dog-leg ring spanner and give them a tug. use the ring end of the spanner otherwise you'll just round off the nuts then you'll have a bigGER problem..
if you hear creaking while trying to undo the nut, STOP! & check that you are not cracking or warping the bolt head. that can happen if you over-torque it..
all the best..

trust me ive nearly sprayed a whole can of wd40 on it and still wont budge.. might try some heat nnow thanks for the help

thing is, did you let the wd40 soak in..? adequately..? it doesn't work as well when it's a rush job of spray-wait-2-minutes-then-try..
the heating approach requires a lot more concentration so you can get a mate to help you, with an extra pair of everything; hands, eyes and brains
it does make the difference//

lambda (oxygen) sensor
your engine management (ecu) needs information from the lambda sensor on how well the engine is burning fuel by measuring the amount of oxygen in the exhaust. this in turn tells the ecu by how much more or less to fuel, also based on a lot more information got from other sensors: air temp, coolant temp, manifold pressure etc. all this happens.. before you've had time to cough
so yes, you really do need the o2 sensor, in good and proper working form. get a pic up of how badly damaged yours is. we may be able to advice on whether to leave it as-is or replace.
here's a much much muuuuuuuuuuch more detailed explanation from wiki..

what do i ask for haha? would that have caused any damage?
dark_knight
Member +
wait a minute, the bit you are holding.. it came off the sensor side (at the exhaust) or it came off the other end of the wire..?

there was one side on the decat but the thing im holding came off the other end
