Changed my battery and now I'm throwing: P0171 -> P0101 -> P0138. Any advice?
I installed a new battery and the engine is now throwing - P0171 -> P0101 -> P0138.
I had it scanned it at AutoZone:
- P0171 -System too Lean (A/F Lean, Bank 1)
Secondary DTCs
- P0101 - Mass or Volume Air Flow Circuit Range/Performance
- P0138 - Oxygen Sensor Circuit High Voltage Bank 1 Sensor 2
I replaced my MAF and cleaned the throttle body. Any advice on what my next steps should be? Based on what I've read it could be a whole slew of things - O2 sensor, fuel injectors, manifold leak, or other vacuum leaks.
