I've had this problem for a while now and took it back to Ford to get fixed, this will be the third time I take it back. What could the problem be? I checked the FAQ and gave them the print out of how to fix it but that wasn't it. What else could it be? It idles at about 1 1/2 or 2 on the average, but not always and at other times it fluxuates arout .5 or .6 but is not steady, kind of like I was tapping the gas. Could this be a CPU problem?? Please help!
