K&N CAI issues. All help welcome
Alright so I installed my K&N typhoon CAI on my BRZ I've had no issues with it, but after about 5k miles driving with it installed my engine light came on with traction control light. The next day the check engine light came on so I got it scanned and threw 3 codes
P0171- bank 1 system too lean.
P117B- No DEC definition found see service manual
P117Ø
Subaru won't touch my car because of my intake and want me to drop 875$ on stock everything and they say it may not even be the problem. So I have no idea what's wrong with my car it's almost time to park her for the winter and it sucks because I really want to drive it before hand lol..... so please help me out.
