got my damn light on again...swung by autozone and see what the deal is and they told me it has codes saying both banks are running lean...said it could be the mass air flow sensor...i recently put on a k&n cai and ever since has acted funny... any suggestions

Do not over oil a k&n or you will clog the MAF. Buy an $8 can of MAF cleaner and soak it down on the bench, after it drys out completely bolt the MAF back in and try it

Check the maf

Also, check the bolts on the intake manifold. Someone I know had all of theirs come lose, their cars ET was waaay off and he had a lean on both bank code.

Check the fuel rails as well.

+1 on cleaning your MAF. In addition, check for air leaks on the engine side of the MAF. If air is getting in that is not being logged by the MAF you will get lean bank codes

If you need a MAF get a stock replacement

I was getting lean codes and after trying everything, including replacing the MAF and the O2 sensors, it ended up being a crack in my L76 intake manifold. The shop felt like it was a defect in the manifold from the factory that finally cracked with the heat cycles.
