What I've done is got hold of a stainless manifold and fitted then gone to put sensors back in and the rear one there is not enough room to get it in not without some major fabrication so I blanked it and wired the rear wiring so all comes off front sensor. Fine for a while then light came on if I unplug and reset codes with obd it shows all fine and sensors working fine but if I turn off and start again they dnt work! Anyone got any ideas what to do????
