Hey everyone, I have recently purchased a 2002 WRX with 219k and after about 2 weeks of regular driving my CEL came on. First it came on while I was driving it blinked maybe 5 times then turned off, could it possibly be a misfire? and after that happened I went home and turned it off for about an hour. After letting it sit I came back and started it up and the CEL was on and has stayed on. I work next to a Napa autoparts store and hooked up their OTC Nemisys reader and it asked me for a "dealer authorization code"; so if anyone happens to know the codes I could use that would be great. Also i have oil on top of my engine and can't seem to find where its coming from (I want to clean up the oil to find out but dont know the best way to do so, engine cleaning guide?), and could these issues be related?
BTW I am new to the forum and am just seeking help to keep my bugeye running in top condition and help would be great as far as things to watch for and things to upkeep. Thank you.
