1999 Mazda Miata 4 cyl Two Wheel Drive Manual 43000 miles
The catalytic converter on my 99 Miata with 43K miles was replaced a month ago. Last week, the check engine light came on and I pulled the P0420 code off. Does the computer need to be reprogrammed when the catalytic converter is replaced?
have the same problem?
