acceleration hesitation

[kyled43]

i have a 00 csvt, im getting 3 codes on my c/e light, EGR, Mass airflow low input, and 02 sensors causing the fuel to be to lean, any easy way to fix these problems? this is my first csvt, well first ford in general and idk much about them, but i love the car and i am wanting to try and get a little more power with bolt on adds, any ideas there also?

...changed your O2s. Make sure you know if they are upstream or downstream first.

get some electronic parts cleaner and clean off your MAF
