Vacuum leak, possibly including intake gasket, or fuel filter, or puel pump.

Check fuel pressure and vacuum leaks.

Common problem with a K&N filter and intake. You can try cleaning your MAF sensor first, because the K&N passes a lot of dirt and oil, which contaminates your MAF sensor, and gums up your IAC valve, and throttle body. The other problem with the K&N intake, the increased diameter decreases the air velocity, causing the MAF sensor to less air flow than is actually flowing. This
will cause a lean condition too. Best thing you can do is go back to the OEM intake & filter, and this will fix your lean problems.

You can pick up some MAF cleaner at your local auto parts store. Directions should be on the can. Only use MAF cleaner. It says on my MAF to not use carb cleaner.
