    Hi all

    Completed a track day today which was going really well. Tested new suspension and flat shift and car was motoring.

    Stopped for a short bathroom break and when I got back in my car the EML light stayed on as did the ESP/TRC light.

    Checked fault codes and the following came up

    EVAP purge valve n80 short to ground P1245
    Exhaust Gas Temp G235 open or short to plus P1453
    Mass Air Flow Sensor weak or low signal P0121
    02 Sensor bank 1 sensor malfunction in circuit either P0131 or P0137 (glare on screen when I took photo)

    I am guessing the O2 sensor is also the EGT sensor in the exhaust manifold might be faulty and this could have been caused by the flat shift?

    Would this cause the AFM to read a fault or do I have 2 seperate faults?

    Car runs okish, poss a little down in power and has a rougher idle.

    I spoke to Unicorn before I got it scanned to see when they thought and straight away they said without seeing vehicle it sounds like the AFM.

    Shall I just replace both or does it need more invesrigation work?

    Also whats a EVAP purge N80 valve?

    Thanks in advance
