check engine light on
I ran a check with my code scanner and got p0442 and p0420, one is catalyst efficiency and the other is small emissions leak, I checked my data on the scanner and both my upstream and downstream o2 sensors are reading about the same and fluctuating a lot so is my catalytic converter bad?
