You can buy spray MAF cleaner in a can and clean it. Take it off the engine to clean.

Every car has O2 sensors... No code does not mean they are getting weak. You would change out the first, or front sensor.

Your EGR will also mess with things, get that fixed. You can also clean EGRs before replacing.
