I'm pretty sure i know what is going on but I wanted to bounce this past a few people first.
Have 04 WRX, only mod is the exhaust and wheels.
Just finished changing my spark plugs and I started up the car. The CEL came on. I thought I put everything back together and then I realised I forgot to plug the air intake sensor back in. Scanner shows 102 and 113 are the codes. I'm pretty sure this is just b/c I didn't have the sensor plugged in when I started it up.
I noticed alot of threads related to aftermarket intake. Just to confirm the intake is stock.
Any one else ever done this?
