Check engine light
I bought a 2002 WRX. When i got it, it had an ugraded turbo, intake, and BOV. The check engine light is on and it is giving the codes for the pistons misfiring. The car seems to be running fine. I believe that it is a problem with the air/fuel ratio. I don't know what to do next. Please help.

Check the other posts about misfires. This is a pretty common occurance. I know that Subaru will have a reflash on this situation in the future but when is the question.
