I have* 2002 GT and have never had a problem with it until the EGR pressure valve sensor grenaded and after replacing it the hoses pop off and the car acts like it swallowed a valume.* I dont know what else could be wrong Anyone help?
Please post the full DTC codes. There are 1000's and they each have a story to tell.
Exactly which EGR component are we talking about? EGR valve, EGR vacuum solenoid, or DPFE?
OBTW, if the line keeps popping off is it really a surprise it runs like crap? Are you sure you have the correct lines for the application? If you have used common vacuum lines on the EGR DPFE sensor, those lines can not handle the high heat of exhaust gases.
As a long shot, consider that if the cats are blocked, this would create excessive back pressure in the exhaust. I could see a case where the excessive back pressure would blow the flexible lines off of the DPFE sensor. Also note that the two lines from the DPFE sensor are DIFFERENT sizes.
The lines to/from the DPFE sensor are difficult to inspect due to firewall clearence issues. Perform a through visual inspection looking for split lines. Use a mirror and a bright light.
Consider using a set of replacement lines from Ford. They will cost more $$, but will be correct for the EGR application (DPFE sensor to EGR bypass line only).

im gonna say the dpfe sensor since hes talking about the pressure sensor. but im with burns on this one about not using correct rubber/silicone lines from the manifold to the sensor
