HELP 2000 expedition 4.6 HO2S problems
My 2000 expedition 4.6 with 127000 miles recently started acting up. It started the day after state inspection. It blew fuse 23 which is for the HEGO sensors, canister vent, automatic transmission and cms sensor and the check engine light came on. Went to autozone and it gave 11 codes all of which were likely from the fuse blowing because it said all four HEGO sensors. Replaced the fuse and cleared the engine light ran fine for awhile and then the engine light is back on saying P1000, P0141, and P0161. I read that it is unlikely for 2 or more of them to go bad at one time and the fuse keeps blowing. Another thing I noticed is that when I first got my truck there was pressure when I removed the gas cap and now there is not. Is seems to be running rougher and sounds like it may have a miss. Use to be ok on gas, compared to the durango I owned, and now it is sucking it up fast. Hope someone out there can tell me where to start.

Update: I found and fixed the problem today. It was bad wires on the passenger side sensor that comes out from the catalytic converter. The wires in the back of the connector were pinched against the metal body of the truck. The one wire was all but cut in half and the other wire was rubbed bare. I cut the wire that was cut the rest of the way and used a wire crimp to join it back together and then I taped the other wire where it was bare and plugged it back together. Started my truck and ran it around for awhile to see if it would blow the fuse and it didn't nor did the check engine light come back on. Just wanted to let everyone know so that if anyone else ever encounters this problem of their truck repeatedly blowing fuse #23 under the hood they know where to go with it.
