After racing a camaro 4th gen, and winning.. Of course. We pulled back into the parking lot and my car was running rough sounding like an exhaust leak or small knock? i called a buddy and he said it could be the throttle bodies out of sync, anyone hear of a car acting like this in general? Thanks
Those codes are all related to richness / O2 sensor. I doubt it is throttle bodies on an '01. One thing to do, assuming you don't get out and run the car that hard every drive, is to just drive it and see if it clears up. An extended run at WOT may have engaged some fuel table settings rarely used (and not optimized hence the black excessively rich condition). You may have an O2 sensor going bad too. That is a 13 year old car Rock Auto has the OE Bosch sensors cheap. A PCM reset could also be a cheap thing to try.
What mods are done to the engine including any SCT tuning?

How many miles? Is the battery fresh & good? If all plugs looked bad and running rich on both banks, I'm going to guess it's a fuel delivery issue. You should test/check the related components: TPS, MAP, clean IAC while you're at it.
I've seen more TPS failures than MAP sensor failures, especially if it's dumping too much or not enough fuel on throttle stabs - it has heavy influence on those fuel values. For some reason the TPS is the last sensor to throw a code unless it's grossly out of range.
Where's the TPS at? I bought some O2 sensors but have to wait till tomorrow for a lift it did the same thing to plugs. Tried another map sensor no luck and I unplugged the 3plugs at PCM for about 4 minutes.
The best way to reset the PCM is to disconnect the + battery cable at the battery and short it against the frame. Disconnecting the 3 plugs at the PCM takes 24 hours to work and then it is even iffy. That info, from Chuck Tator's input.
