Computer went crazy!

Hello guys, so the problem starts when i leave my interior light on a few hours and my battery was dead, after that i ask for help to a friend to recharge my battery with his car. My car start and everything was ok, until the next morning. My cant wont surpass 2k rpm and the brakes lights still on, after I turn off my car. A friend suggest me to disconnect the battery for a few minutes and connected again to reset everything, but now is worst because keep the same problems and in addition my windows come down completely wen i open the door, And the car can start with out press the brake. Its went crazy, any suggestions?. What i need to do to fix this problem?

The interior "map" light should not have severely discharged your battery after being left on for a few hours. That tiny bulb does not draw that much current.

How old is your battery? If it 2-3 years old, or older, you should have it tested to make sure it is not going bad. At the very least you should get it fully charged before your next trip. Once the battery starts getting weak, all sorts of oddities happen with these cars...

P2A03 refers to a fault with the Bank 2 (driver side) air/fuel ratio (A/F) sensor:

Separate issue from a dead battery. Could be anything from a bad sensor to a air leak. I doubt a clogged/damaged catalytic converter would set this code but I can not say for certain. What makes you say the "cat" is bad?

Charge your battery, reset everything, and go from there. If the code sets again, then you know where to start.
