Ok my check engine light goes on an off. I got the code pulled yesterday and it says that i am not getting enough air on bank one. Could it be a air flow sensor or a bad cat.

I would make sure your MAF sensor isn't dirty.

Also, might help if you posted the actual code that was thrown.

Yup ... 99% sure it is a dirty MAF sensor. Go buy a can of maf sensor cleaner from autozone or where ever. Take maf sensor out and spray it clean ... Wait for around 15 minutes and then reinstall. Disconnect the battery for 10 min to reset the PCM. Connect battery and then start car. Enjoy

Whats the exact code number? Not enough air as in it's "bank X too rich?" yes?

Could be a lazy o2 sensor..
