1.2 8v c12nz dizzy type lump, there is slight hesitation when setting of and a dip in the revs only just noticeable when first changing gears you have to touch the accelerator to give it 'push' . it does not cut out im being a little picky but my other 1.2 8v wasnt like this it has had a full service new CTS and everything else - have noticed the idle is also slightly rough as well its all pointing at a duff oxygen sensor from what i have read - it is nigh on 20 years old now but only done 68,000 miles ..

i just thought it may be worth asking for a second opinion ? possible lambda sensor on exhaust manifold at fault?

cheers

First check you exhaust system very thoroughly. Any leak anywhere in it has that kind of effect on them - or even if the baffles have blown it can do that to them.

You'd need to hook it onto a diagnostics to know for sure if the Lambda is working accurately.
