I took the intake manifold off to check if all wires were connected and to anything strange and found what was a nice clean head now covered in brown sticky residue. I could see the stuff had run down the inlets and covered the valves. Also around the injectors there seemed to be fuel. Like I said the engine revs very well after idle. So

1/ the timing is out blowing back some through the inlets at idle. I doubt

2/ There was hardly any fuel in the tank back in Oct 2012 when I took the Mini off the road so maybe the fuel went off in the tropical heat and maybe gummed up the injectors until I added some new fuel.

3/ the ECU tune is dumping too much fuel at idle.

Is it possible ecu tune some how canceled out the rev counter and temp gauge?

 

More checking last night revealed a small plug not quite pushed in, got the Tach and temp gauge working. Yes it pays to double check. Engine runs better but I think the fuel system needs a clean out now.
