changed my faulty cat on friday car seems really good now 😃 did check on my snap on scanner the readiness functions and its still showing the catalyst as incomplete even after a 70 mile trip it still shows incomplete on the live data the pre and post o2 sensors are present and the post cat sensor reads 000 volts with engine off and gets a voltage reading when car is running car seems ok no probs or eml is this anything to worry about or has anybody got any ideas?maybe post cat sensor not working? if so what problems could this cause any help would be great cheers..
