I have p0421,p3081,p1696,p0300,p0301,p0306,p0307,p0302,p0308,0303,1570,1423,, but my car runs great.. Not a lot of power like when I first brought it.. Just can't keep the check engine light off,comes back on in a day or two..
Make sure your air flap solenoids are working for the flaps in your intake manifold. I had crappy acceleration and found my diaphragms were not sucking down at idle due to both solenoids being bad.

The easy way to test of your flaps mechanically is to disconnect the vacuum supply line and while running at park, apply vacuum to the diaphragm vacuum port.
