Need some help guys, Im lost?? I need the Experts.

So here's the deal I installed a K&N cold air system and everything was working fine for about 6 months and then out of no where I get code of
P0101 pops up. So I pull the K&N and Clean and re-oil it and install. Get the P0101 again and I got informed not to oil the K&N because it gets oil on the MAF causing the code. So I re-do all of this and it works fine for about a week and then I get a P0174 bank 1 running lean, and also I got P0171 once also. So my next move is to pull the MAF and clean it with Brake Cleaner and make sure its %100 dry before re-installation. If there is anybody out there who knows what I need to do to get these codes to leave me alone I would be in your debt for life. Thanks a ton guys in advance and I hope to hear from you soon.

Ya clean the MAF with brake cleaner, while you're at it clean the TB with TB cleaner

I agree with BOSS, get that MAF cleaned, you probably got filter oil on it. Doesn't hurt to clean the TB while you are in there as well.
