HSE 4.6 Gems. Failed the MOT on emisions - CO2 way too high (also on rusty NS sill but that'll be welded)
Nanocom shows that bank A O2 sensor isn't switching, stays @ 4.23v, whereas Bank B alternates between 0.03 (from memory) and 3.25 ish. The long term trim on bank A is 38, and on bank B is 6.4v (again from memory).
Would this make the mixture on bank A rich or lean? It could possibly explain other issues.
