Default 02 and STFT lean codes

Im trying to track down possible causes of these codes. I keep getting Bank 1 and 2 STFT lean and o2 sensor bank 1 and 2 codes. at first i thought they were from leaky connections at the collectors, but after resolving the exhaust leak, the codes still come up. anyone got any ideas as to where to look next?

I had the same codes. Mine was from the exhaust leaking and the pcv hose was cracked from dry rot I guess.
