I had a slight loss of power but turned car off and waited an hour or two then it drove home fine. I drove it to auto zone the next day to get a diagnostic and the P0420 and p0021 codes appeared I'm just wondering how urgent it is and what the repairs may be?
Vehicle:
2004 Nissan pathfinder v6
p0021
p0420

P0021 Intake valve timing control solenoid valve
P0420 Catalyst below threshold Bank 1
Having a timing control code the engine goes into a fail safe operating mode, When the CK ENG LT is comes on and the component involved is a solenoid, left the way it is not only do you have limited operation but you can burn out the ITV solenoid driver in the ECM. As for P0420 your the length of time depends on your emission test for the registration.
