Have a 2003 XLT with the 5.4. Power is down, sometimes when stressed uphill or light towing the service engine light flashes and it goes into a kinda "limp mode" during that time the A/C turns off and it won't accelerate, lasts about 30 seconds light stops flashing then it accelerates again. Mechanic changed the plugs and packs, said everything else looked good, though he couldn't find the fuel filter anywhere, but he did get some low readings from the cats so he believes they are clogged. Being a 03 with 240K, and I don't really have the money I don't really want to buy new ones. So if I remove them or punch them out what am I looking at, anyone have real world experience removing them? I'm sure it'll trip the service engine lights but will it still run normally especially since the 02 sensors will be useless? I am in South Carolina, no inspections so no issues there. If this is an option whats better punch them out or replace with pipe? He did bang them a little to loosen them up and I bought some Cataclean I am going to run thru and see if that works with some high test, just looking at my options. Thanks all
