Not sure what the sound is but when going up a hill it seems like it starts backfiring and losing power. Can't tell if it's something simple like spark plugs or something else. 02 sensor and knock sensor for codes are pulling up. Just did fuel pump and lines

Re: 96 sedan deville

How old are the plugs & wires?
Have you checked the fuel pressure?
FPR?
Vacuum leaks?

P.S.
I edited you title. 96 Sedan Deville isn't very informative.
