Lincoln Continental: Kenny, I have a 99 continental and replaced

Customer Question

Kenny, I have a 99 continental and replaced the cat's about 17,000 miles ago. I was driving recently and suddenly lost power like I did the first time when the cats failed. I discovered that the DPFE sensor had been melted and blew off the vaccum line. I replaced that but it seems like there is still a lack of power. I put about 1200 miles a week on this thing and don't want to be stuck out in the boondocks again. I did run some Cataclean through the tank and it seemed to help but I am wondering if the bad DPFE has damaged the new cats? can you give me some direction to start looking? Thanks

Hello my name is***** and thanks for your question.
It sounds like the cats are plugged again. Usually a melted DPFE is a clear indicator of restricted exhaust, the exhaust backs up and melts the DPFE.
