stumped with evap system

[dedezgoin]

Upon checking my free computer check at advanced a.parts, found:

p2270 -O2 sensor stuck lean B1 S2
p2271 -O2 sensor stuck rich B1 S2

PO45s -evap system leak detected (gross leak no flow)
PO13e -sensor delayed response Rich to lean (bank1 sen2)

if I replace both O2 sensors do you think that could resolve my computer issue?

Before jumping onto the parts wagon, try another store like AutoZone if you didn't reset the error codes. It's better to have a second scan of the codes are correct. They won't go away unless something changed like scanning the first time on a cold engine. It's presumed the check engine light is on to tell you something's wrong?

And the latter two error codes - all error codes have a letter followed by for(4) numbers, not ending with 's'.
