P0174 System too Lean (Bank 2)
What exactly does this code mean? I clear the code and it eventually comes back of course. Was told it might be either a vacuum leak or a problem with the MAF Sensor. Wasn't able to find a leak and cleaned the sensor with some CRC Mass Air Flow Sensor cleaner but it eventually came back. No drivability problems, truck runs perfect, just annoyed with the check engine light.
