Hi,
My daily driver 350z (my06) is failing to pass the MOT emission test and I'm not really sure where to start in getting it fixed. First place seems to be the O2 sensors as I've been getting engine warning light from both sides:
bank1 Sensor1 - P2A00
bank2 Sensor2 - P0157
I had Cobra HFC fitted 18 months ago to replace originals as they had started blowing at 135k miles (now at 150k miles). It passed the last MOT just fine but soon after, 11 months ago, the engine warning light came on.
On a recent post here, I read that there is a vent/vapor pipe from the fuel tank back to the engine in-take and that can effect the emissions if split. That's very interesting to me as I've been getting petrol fumes coming in through wound-down windows on long drives that I've not been able to track down.
I'm based in Southampton and am really struggling to find a mechanic near here that actually knows about Zeds.
Any help would be gratefully taken at this point. Need my 350z just to work as it's my daily driver.
Thanks Antony
