It drives fine but when I give it gas it sounds like its forcing it seems to drive faster but won't push out much power. And will decrease speed up hill I have been told it could be a vacuum leak or the mass air flow sensor. But I don't know how to fix please help.

P1505 Idle Air Control Valve Opening Coil Voltage Low.

P1507 Idle Air Control Valve Closing Coil Voltage Low.

I don't have a listing for the other codes. Since you described it as "it sounds like it's forcing" Have you checked the catalytic converter to see if it is plugging? As far as the two codes I listed, that would cause an issue with your idle.
