A while ago I had some problems with my Catalytic converter where it clogged up. It resulted in an extreme loss of power and in two hoses blowing off on a consistent basis. These are just two 1/4 inch hoses about 1 foot in length that come out of what looks like a sensor. The sensor is located right below the upper intake plenum on the drivers side and looks like a box with two hoses coming out of the bottom. Any way, I have replaced the main catalytic converter on the bottom of the car. My car now has all of it's power back but the hoses are still blowing off. I clamped the hoses off at both ends and they are fine until I hit about 4000 rpm and this will always blow off the bottom connection of one of the hoses. I know that I still have a clog in my exhaust system but I do not know where to look now. Any suggestions would be greatly appreciated.

Take the exhaust loose behind the main convertor and rev the engine to see if the dpfe hoses blow off again. if they do, replace the hoses with new ones (get them from the ford dealer; they are a special hose) and try again. if they still blow off, suspect the upstream catalytic convertor on bank 1.

EGR monitor, look for a clog down stream. iirc the egr tube comes after the pre-cats on the y-pipe. thats how it was on my lincoln. get new hoses they are a little stretched. f250 4x4 muddin anyone?

Take it to a dealer, as your cats are still covered under the 8yr/80k mile warranty. "Those who cannot remember the past are condemned to repeat it" -George Santayana
