Help! Car isn't pulling quite as strong

[NickTheTrick]

I've had my Check Engine Light come on and off once of twice in the past few months, and now it stays on most of the time. '89 red isn't pulling quite as hard either it feels like.
Codes:

91 - 02 Sensor
Not switching SS1 Circuit Fault


41 - EGO
Not Switching Lean Exhaust

I haven't had the car a year yet. It has 192XXX

Time to do O2s is what it looks like.

 

[Irish Pride]

If you have an o2 failure the injectors will be dumping fuel into the engine. I'm guessing your MPG has been worse too lately.

 

[NickTheTrick]

Yeah, it has. I'm going to change the O2's withing the next three days. Thanks

Are you down in the Petersburg/Colonial Heights area?

If you don't have one, might as well do an equal length y-pipe with hi flow cats along with the O2's. If it's been running rich for some time, the catalyst in the old cats will be contaminated with fuel, clogging the flow.

Yeah, I am.

Good point. Thanks for the advice.
