Quite possibly. Get a CO test done. If around 5% you need a new sensor.

I've not been in for one yet Peter, going to book it in for an mot later on today, cars been off the road really, fixing other issues that have popped up. The old lambda sensor had a Nick in the cable too which isn't good...

Edit: mot tomorrow 3pm
