Hi guys.
My S14a was off the road for 1.5 years, with only occasional startups, and I want to get back on the road.
I naively took it for an mot straight out of the garage and it failed on emissions as below.
Fast idle:
CO 1.77 (0.3 max)
Lambda 0.954 (0.97-1.030)
Natural idle passed.
Full report here (if link works):

I have given it a full service, emptied the old fuel, topped up with new and added some emissions reducer. I want to change the o2 sensor as well, but the thing will not budge (o2 sensor socket).
To those who understand emissions, is there anything else I should do and do you think it’s worth changing the o2 sensor?
Also, what has worked best for you getting the o2 sensor off? I have got a crows foot spanner on order.
Thanks.
