Hi all its my first post so please be gentle.
I've got a 2016 Leon 1.8 petrol and i am getting a intromittent P0420, the idle feels rough and there is some fluctuation in the RPM needle around 1mm fluctuation it feels like a misfire without there being a code or any indication of a misfire on the OBD misfire counter. It drives fine no hesitation and plenty of power when accelerating. No visible smoke from the exhaust. Seams to be using a bit more fuel than normal.
Mileage is 55,861
Serviced 2 months ago.
Also could anyone tell me if the Pre cat 02 / Lambda is a wide band sensor as it has the 4 wire connector and not the 6 wire that would normally indicate a wideband sensor. The reason for asking is the 02 sensor V reading is not in the V range i would normally expect.
Any advice would be appreciated.
