Hi just wondering if anyone can help me. My AUII is missing at idle in gear and out. When I slow at the lights and it changes back to first it gives a shudder and the idles drop to about 400rpm. It doesnt do so every time but 60 percent of the time. Someone suggested it was the idle step up motor which I have had replaced( the car idles in gear at 500 to 600rpms) it has made no difference at all except idling in gear is a bit higher. We have done plugs, leads (just had the fuel regulator replaced cos it was overfueling).The longer you sit waiting at lights etc the worse the miss gets but normal driving the car is fine. Fords have said they cant find anything wrong. I dont know what else to do!
