Engine Performance problem
1999 Honda Accord 6 cyl Front Wheel Drive 192000 miles
I just diagnosed my car and 4 codes came up.
P0420: catalytic effic bank 1> The catalytic converter on the car was changed 2yrs ago when I bought the car because the engine light came up then. But after it was changed the light came up again and the mechanic told me it is O2 sensor that needs to be changed.
Others are P0401, P1457 and P1739. Of all these, I want to know which one is dangerous and should be done first.
The mechanic that checked the engine turned the check engine light off but said it might come back up. If the light come back up, which of these problems should be worked on, pls?
have the same problem?
