We had a problem with FORD too. They supposedly replaced the pre-cats, then later the catalytic converter.Hmmmm do you actually think they did? Cause ummm, we had to gut the cat since it went bad, and my pre-cat closest to the firewall has a hole in it, preventing the o2 sensor from reading. Coincidence? I think not! What we did end up doing is taking it to my husbands friend at the mercury dealer. Got some stuff fixed and they ran a scan on it for free *thank gawd* to see why its actin up. In all honesty, I will not ever go back to the ford dealership. They tend to wanna ream you a new one each time, as you can already tell.
