Hi all,Some of you may have read the wifes gl has been playing up.I replaced the lambda sensor and engine temp sensor yesterday and still the same :sad:A friend of mine took it to his friend at kwik fit and the plugged it in and it came back with Hall sensor.Is there a link on how to change this or can someone tell me,I have had a look but there is a metal disc in the way and it doesn't seem to want to come off lol.
