Answer 1

Did you have work done on the car recently?  Air filter replacement? if no try use a higher octane gas (91) if you dont already. also if your car is still under warranty you can take it to the dealer

other possible causes:

-Faulty spark plug 2
- Faulty ignition coil 2
- Ignition coil 2 harness is open or shorted
- Ignition coil 2 poor electrical connection
- Clogged or faulty fuel injector 2
- Injector 2 harness is open or shorted
