the sensor is really easy to do anyway they just cut a small hole usually with the oxy torch and then weld a nut with the right thread over it. It is only like a 5minute job if it is eay to get to.

like everyone has seemed to say. you don't need it to run.

but get it done, you'll save a packet in fuel costs.

wideband ones can only be used for tuning as, apart from what chris said, they have a much shorter life span (20 odd thousand km's)

cheers for all the help guys, i'll book it in to get sorted this week, hopefully the slacker of an exhaust bloke only takes 5 minutes, its his stuff up, so he's fixin it

i'll post sum pics of the ute soon, not painted yet
