Well, I took my car to a ford dealership to get the cats replaced (pulled the crap out of my ypipe), and yet ford says it was the hoses on my DF4E sensor (that I replaced the sensor itsself and was getting the correct reading). Now Ford says my cats are fine (remember I pulled the cat material out of my ypipe), and it was the hoses on the ypipe.
What do you guys think??
Can the DF4E hoses KILL topend power, even tho the sensor is reading correctly?
And how in the hell can your cats be ok, if you have the cat material rattling around in the ypipe?
