Check if there is damage to the MAF sensor... Sometimes if the MAF is damaged or is malfuntioning it will run better with it unplugged.

Also check the MAP sensor and be sure your intake is fully tightened down. Some here have had a couple bolts on the intake loosen up over time and make it go doing goofy things.
