It's strange as the coil pack is new however I have heard stories of 3rd party ones not being as good as the ford ones. Do I really need to go and spent £140 with Ford for a genuine or does anyone know of a cheaper brand thats had decent success ?. Either way I'll wait till the noid light comes and I can do some more testing. I was also going to take the lid off the ECU to see if I can see anything burnt out however I can't work out how to remove it from the car as the plugs look like they have a metal bracket round them with a rivett or security screw holding it in place. I can't even get enough slack on the wires to slide the ECU down out of the black plastic bracket?

Any ideas ?
