I just picked up my new baby 2007 Satin Pearl White wrx tr, and It has a problem or two.. I have two codes from the check engine light. P0243 and P0244. Something about the valves being open and closed?? I'm a newbie when it comes to cars and especially subarus. If anyone can help me fix this problem it would be greatly appreciated! also I just got a new code as well... P0137. effff. thoughts?
