I'm trying to pass emissions but the car keeps throwing a P170 code: fuel trim Malfunction. I'm not sure which way to go to fix the problem. I'm running stock injectors but I've installed a walbro 255 fuel pump and have 6AN line running from the fuel filter to the fuel rail. I'm also running a Fuel Lab AFPR adjusted to 42.5. I have a 2G Eagle Talon AWD with 6bolt swap and JDM Cyclone intake.
