Hi all new to the forum. I recently had my y pipe exhuast remade to fix a blow and EML light. So having driven the car the EML returned with codes for bank 1 sensor 1 O2. Cat efficiency code has gone so not like the exhaust didn't need doing but slightly annoying it didn't fix the primary o2 sensor codes but not surprising. New Denso sensor has been ordered so I will get that on ASAP as it does smell a tad rich while it's running still. On the other hand I'm quite pleased it's still needs the o2 sensor as the MPG hasn't been great!
I'm correct in thinking bank 1 is nearside/passenger side aren't I? Also what's the best way to get to the sensor as access doesn't look great? TIA!
