Default P0303 Code

My stage 2 2002 WRX with a 2.5 hybrid engine is throwing code P0303. It idles fine and doesn't show any signs of misfiring in low rpm's. The only time it sputters is when I am over 50% throttle and hitting boost. Any idea what the problem could be? I had the swap done about 30k miles ago and this is the first time I have had any problems.

Thanks,
Scott

I just cleaned up my engine using degreaser and a slow flow of water and if made the problem a lot worse. Now the CEL is flashing. Any ideas of what it could be?
