mass air flow sensor
Just a few days ago i replaced a bad O2 sensor and now my check engine has come back on (P0101) and its saying that my mass air flow sensor is bad. I never had this problem when just my O2 sensor check engine light was on and I was wondering if the bad O2 sensor was keeping the car from noticing the mass air flow problem or are they two separate issues?
I know I need to clean out my K&N cuz it has was too much oil on it and that may be the problem too and i just ordered a new lid with a K&N filter so hopefully when i replace it the problem will be fixed but does anyone have any ideas?

Sounds like some oil got on your MAF. I would spray it with some electrical contact cleaner or CRC makes a MAF cleaner spray. Just spray it down, let it dry. Reinstall it and you should be good to go.

If the code was P0102 first thing I'd check is the ENG SEN fuse for an open, MAF and 02's are on the same circuit. Check it anyway, only takes a couple seconds.
