thanks for your help i originaly did a fault code check and got 12 and 34 i have now checked it and got 11,12,21 and 34 so i have re connected the orange wire and it seems ok :? :? but all the codes were still present so i borrowed the ecu of my black r and ran the engine for about 5 mins there are now no fault codes present do you think it just hasnt picked up the faults yet as i havent done anything to solve the problem :?
