Need help! running lean

Alright i pulled all my trouble codes and i had about 6on a 1999 Trans Am. here is the list, bank 1 lean, bank 2 lean, knock sensor, high idle, bank 2 cat, and bank 2 O2 sensor 2.

The car does not seem right here is the symtoms... sometimes low idle around 500 rpm, sometimes high idle at 1100 rpm. lower fuel efficiency. less power. right cat rattles at around 2500 rpm.

I need help in what i should do or check. I do not know where to start, if anyone could help me i'll greatly apprieciate it. Thanks

whats the cars mods and any recent repairs or maintenance done to it? sounds like a vacuum leak or possible fuel restriction.

Sounds like the passenger cat is toast along with the o2sensor. And without reading the ECM it's hard to be sure of other problems. Get somebody to scan the car.

Did you scan the motor or just pull the DTCs? The codes all present? Old history?
Going to have to throw the dog a bone here. Try searching the DTC codes out for causes.
