The car failed emission test because of the trouble code P0420. I replaced the CAT and reset by OBD scanner and disconnected the car battery, then drove about 500 miles, brought the car back for emission, but it was not ready for test since some pending codes like C, EV appeared, what should I do now to get the car ready for emission test? Please help.
have the same problem?
