hey guys, thanks a lot for all the help and input. I ran codes and this is what I got: PO174 - System running too lean bank 2

I went ahead and bought a new fuel filter and MAF cleaner, And I am very suspicious of the cheap intake so replacing it with the stock intake plus new K&N air filter. And taking a look at the DISA What else do you guys think I should consider?
