Answer 1

check for a intake leaks by the intake manifold, or crack in the intake tube, Also check fuel pressure. You can also add a fuel additive to the gas tank or do an injector flush 

 

Possible causes

- Faulty Front Heated Oxygen Sensor Bank 2
- Intake air leaks may be faulty
- Exhaust gas leaks
- Front Heated Oxygen Sensor Bank 2 harness is open or shorted
- Front Heated Oxygen Sensor Bank 2 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
