Welcome to the forum.
It's probably not the O2 sensors. The two most common causes of these codes are 1) A cracked PCV hose elbow. Usually where the hose connects to the rear of the intake manifold. 2) A dirty MAF. It is located in the intake trac just to the laft of the air filter housing. If you look into the air tube, you will see it. It has 2 small wires at the top. Spray them with electrical contact cleaner. Do not touch them, they are very fragile.
Hope this helps,
Jimmy
