Check Engine Light Help ?!?!?!?!?!?!
 

My check engine light is on and went to AUTOZONE and this is what they gave me.

P0140
The PCM has determined that there is insufficient activity from oxygen sensor 2 in bank 1 for current operating conditions.

P1457
Unable to pull vacuum in tank.

Can any help as to what exactly this means, how do I fix it, and how much will it cost me?? Any help is greatly appreciated.

check the gas cap. if it isn't sealing, no vacuum. is the seal on the cap look ok? you need to tell us more about the car. 4 or 6. miles. year.
good luck
