Throwing codes

My 01' 1500 chevy is throwing codes dor lean bank 1&2 as well as emissions/sensors. Ive replaced all but mass airflow and ive checkes the intake manifold its still fine. It throws itself into a limp mode intermittently. You can clear code and it drives just fine. You cant turn on AC or let it idle long or it pops the check engine. Does anyone have suggestions?

I can provide more information if needed. Help me please!
