Great Daz, yes put the Brown wire back on the timer, Cold start idle does sound High, should be depending how cold the weather 1100 /1200 rpm...gradualy drops to preset Idle 850/900 rpm, If it does not get back to me how to set up....but as you said you have plenty other things to sort first, once your at a stage on the road and find the Hot idle bad, remember that 5th injector was cut out for a reason, can help on sorting that, remember the Brown wire must not remain earthed, it should be back on Timer, you see Timer cuts it out when Warm.......... main thing now is its RUNNING..
