Not saying you did it, but another reason to not replace a narrow band sensor with a wideband while tuning . At least then you have a check whether it is at least in a rich zone in pe.

Oh it was definitely my fault, I've been slowly learning to tune on it so didn't spot the narrowband not lining up with the wideband till a lot of diagnosis

My response was directed at some recent post of replacing the narrowband with wideband while tuning. And the more time I spend on HPT forum, the more that I see aftermarket widebands need something to verify against.
