When I was getting my gauges put in I had problems with the grounding of the car. The ground does not seem to go through properly. When I was getting it fixed I found out that the Ford Falcons have problems with the earthing and a couple of the auto electrician advised this is a common problem with the Ford.I would probably start there. If you know a sparkie or a hobbist, just get a multimeter, set it to ohms and them touch the negative terminal of ya battery to a parts of the car, if there is resistence there is a problem. My car had differences between different parts of the car and engine.I was told by a couple of auto electrician that the Falcons seem to run a little rich if they are not grounded properly, this could be the reason for the dirty butterflys Since I have had me car back from the sparkie, it runs better and even idles better not perfect but a lot better!!!!
