View Full Version : Check engine light

I just bought an 03 WRX, so I decided to disconnect the hose that returns the BOV air into the turbo inlet. At first the check engine light didnt turn on, now it is. Does anyone know why or should I have not done that?

Put it back. You are letting in unmmetered air into your intake. And you will have to read the code to know what it is.
