Car running bad ... help please..

[Dysfunction]

Just something about the 02 sensors. One of mine went out and the only reason why I knew was because of my Air/Fuel gauge. I mean the stang bogged a lot and also surged but no CEL came on. My MPG dropped that bad when it happened. Thats just my experience.

It wouldn't surprise me if mine were going or gone. Thanks for the info. I haven't driven enough miles since last week to check mpg but it feels better just from the aforementioned. This is something on my list anyway. It's quite a long list at the moment...

how long after you replaced the wires cap etc did it begin running bad?

Actually it began running bad after is did the x-pipe. Had to cut the smog pipe going into the stock cats, then plugged it so it would stop making crazy noises.. then the smog pump started making crazy grinding noises, so no there is a new belt bypassing it altogether. Runs better.
