If it hasn't been changed lately, it would be a good idea to replace the fuel filter. Although I don't think that is the root of your problem, it can restrict fuel flow and cause problems when you exceed the fuel demand it can flow.

Let us know your status after completing those items.
GOOD LUCK!
ok i took the whole CAI off cleaned EVERY SINGLE piece on it even the rubber pieces and i washed the intake tube inside and out and i cleaned the air filter with the APC cleaning kit although i have a k&n filter but it came with the red dye anyhow i looked under the car and the driverside #1 o2 sensor wires were tore in half i fixed them and i made sure that i secured them so nothing could grab them again!! i went and bought 1/4 in gas line and fixed the vacuum line that runs to the back of the plenum that would clamp itself shut when i revved the car and i erased all the codes yesterday and none have showed back up!!! but i dont know if im getting all my power?? i haven't drove it in 2 or 3 months maybe im not used to it?? but i used to do burn outs in 2nd gear when it was NON PI and now it barks and chugs down if i do it now!! i called summit about my spark plug wires and they are sending me new ones!! ill install them tomorrow and post if i get more power from it!! i just had too take them s/p wires on and off 10 times before the machine shop got my heads right maybe i messed them up?? also my mass air flow sensor has a small hole (size of a Q tip end) with the little wires in there and i had no clue how to clean them?? and i sure didn't try without someones advice?? ill post again tommorow
