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.

strange it would coincide with the battery change. did you clear the codes/....which ones came back?
