2003 Volkswagen Jetta 4 cyl Front Wheel Drive Manual 99980 miles
i have 03 jetta with rebuilt engine just installed and p0420 code pops up. So I replace both o2 sensors and new cat. What should I do next this code is haunting me and I have to pass az emissions. Dealer says clear code and drive for 200 miles to cycle the computer but engine light comes on at 40-80 miles thx
have the same problem?
