it could be multiple things that are causing this problem such as - Exhaust leak
- Improperly installed or loose Exhaust Gas Temperature (EGT)
- Low engine compression
- Corroed fuel injector
- Water in the fuel system
you can start with the loose clamps or checking for an exhaust leak but i would recommend that you take it in and have diagnosed or you are jyust going to be playing the guessing game throwing parts at it
