How many times during your many calls did i ask are you sure teh sensors wired up right and working? Guess why i asked? Cos lack of or incorrect lambda signal is signified by rich idle on my software, thats how i set it to work, so your first clue is failed MOT.

The instructions even told you what colours to wire up where! What were we saying about CuNTstomers only teh other day James?

It sounds like you have either grounded or applied power to teh signal generator, not to mention covered it in oil, so you may as well just buy a 3rd one.

I wonder what you were sending to pin 2 of your L8 then?!!?
