In some VQ engines with P0011 or P0021 with a possible P0300 stored and sometimes a cylinder misfire. The cause may be the Intake Valve Timing Control Solenoid. If the Intake V.T.C. sprocket is not in the correct position at the correct time because of Solenoid malfunction, incorrect valve timing could occur, causing the symptom.
Look for a cylinder misfire that is isolated to only one bank of cylinders. In your case will be bank 2. Check the function of the Intake Valve Timing Control Solenoid for that bank. If is necessary replaced the solenoid valve.
