Mat I really know how you feel mate I have had enough of helping every other fucker out but when i want a few hours help everybody's busy....funny that as I was busy when they asked for a hand/ help but dropped what i was doing as they were mates/ family
anyway rant over.
its an easy enough job to do the lambda mate ( if i can do it any body can) you have a black wire that goes to pin 2 on the ecu and 2 white wires 1 goes to a earth and the the other goes to ignition live and thats it!!
If I was close by I would come and sort it no probs mate
