I have a slight problem. I have a 2002 WRX. I've had it for nearly a year. About a month after I got it, I put an AEM CAI on it. This was before I'd read everything on this forum about how a CAI isn't exactly good for a WRX. Regardless, I liked it and I left it on there. I had absolutely no problems with it. Then about 1 month ago, I got a Borla Cat-Back exhaust. I love the Borla and everything was going fine. However, today I got a CEL. I realize that I'm probably running a little more lean than I would be from the factory on account of the intake, but the thing is so rich from the factory anyway right? Well, I'm not sure why I'm getting the CEL. Once again, all I have is the CAI and the Cat-Back. Any help would be greatly appreciated.
Thank you.

Well, I got the code from AutoZone. It's P1443, Evaporative Emission Control System Control Valve. The guys at AutoZone told me that it probably has something to do with the fuel overflow tank. However, I just got back from driving and the light didn't come back on. Whatever.

 

had the same CEL, fixed under warranty.... nothing to do with exhaust.

 

Did the dealer tell you what the problem actually was?
Do you have any mods?
Thanks.

I have a gutted stock up-pipe, Stromung Axle-back and a bunch of suspension mods. This is what the repair invoice said:

"Warranty - ORVR Evaporative Vent Control Solenoid Valve replaced"
