We can continue here if you like no phone call is needed if this is what you are speaking of.We can continue here as much as needed.Let me know if this is something you would like to do.
One of the more common causes for this fault here is one or more injectors not atomizing properly in the intake.I have seen these act up before needing replaced or in some cases cleaned.I have had to clean the injectors on this model several times before for this fault here as well as replace any that would not clean up on this engine.
The other issue I have seen is the EGR valve can stick open and cause misfiring and rough running.
If you have not had the fault codes checked to see if any codes are set in any of the computers this needs done.If there are any codes set this will help in diagnosing and locating the fault here.
Fuel injectors are common as well as a stuck open egr needing replaced.But fault codes do need checked and further testing.IN some cases adding a bottle of injector cleaner to the fuel tank and running to near empty and repeat will help clean up the injectors.
