Hi guys got a problem with my let. Noticed today that the lambda sensor is staying on pernament. Car was turned off 8 oclock this morning come to it at 1.30 and its red hot.? Could it be wiring related.? Someone said ecu playing up?? Any help would be great.:thumb:

Abit strange , has the wire been cut or lengthend and maybe got crossed somewhere , I opened the loom plug onto Ecu and found 6/7 wires all melted together and corroded, maybe worth a look, is your switch live to Ecu , switched and not just live

Not that i know of. Ive just been out and had a look at the fuel pump relay wiring and its a right bodge. Wires cut and spliced/soldered everywhere. Gonna strip it back and re do it all and go from there. Sure someone has wired something wrong somewhere!
