Check engine light came on yesterday and I bought an Actron OBD II scanner. I have a 2000 Explorer XLS V6 4.0 lt Vin X
I got 4 codes from it and are as follows.
From What I know and have read on here it could be the O2 sensors and/or the fuel pressure regulator. I just bought this vehicle 1 1/2 weeks ago and have an extended warranty on it and taking it to the dealer tomorrow. I would like to try and figure out what it is myself so they don't try and say well it's this and that.
Another problem I have noticed is there is a humming coming from the passenger side of the vehicle and it does it when warm or cold. It stops when I rev the engine up but then starts back up whenever it feels like.
