I would have the fault codes re checked with a scan tool that can plug into your vehicle here and can read all computers to see what codes are set.Once this is done any codes set need diagnosed to locate and repair this fault here.You may have a restricted catalytic converter that can cause all of these issues here.I have had to replace the catalytic converters in the past before for this type of fault here.
