Ill start off by saying i have searched threads but nothing i have found was very detailing.
I just bought an 04 wrx with fmi,intake, go fast bits bov, grim speed manual boost controller, and more.
The car was tuned by turn- in ( a respectable tuner here in cincinnati). My problem now is that i am getting a po171, bank 1 system too lean x2, and a po303 cyl 3 misfire. 2 days after buying it the cel came on for cyl 3 misfire, i put injector clener in it and erased the code, that lasted about a week. Today it came back on at a cold start and said both codes stated above. I clered both and they havent retured yet! Both times the cel came on was after a cold start, could they be linked together? I also cleaned the maf sensor and made sure the intake had no bends before the sensor, like some ebay intakes do for the wrx.
Input is highly appreciated guys, thanks!
