Just thought I'd finally introduce myself. I purchased a silver 02' WRX about two weeks ago from a private seller. I hadn't bothered checking the battery out and of course it died on me a few days after I got it because it was five years old. Luckily I had the funds to replace it. The o2 sensor just went out as well acording to the scan gauge. Other then that everything is working including the fog lights. I'm not that knowledgeable about cars but I'm always looking to learn something new. All I know how to do is change the oil on the car haha. The previous owner put in a SPT Short Ram intake, lightglow in the driver & passenger footwells, scan gauge II and a pioneer avh-p3300bt.
