Hi I have a 2003 ford expedition with the 5.4l engine and for some reason one of the hoses of the dpfe sensor got unplugged, this caused the performance to drop dramatically, after seeing the hose unplugged I plugged it back on and my question is if there is a cetain number of miles that I have to drive in order to get the performance the suv had before all of this happened, because after plugging the hose the performance is still lean. Thanks
