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?
