It just started to get slowly worse and worse we had it in like 6 times and the service manager told us he wasnt wasting anymore time on it so we called ford Canada and they pretty much told us to shove it up our ass. Now isn't that great customer service. The only thing we did to it is get command start for it but we didn't start getting poor fuel Milage till several months later, also my friend hooked it up to his computer at Canadian tire and he couldn't find anything abnormal either
