P0420 CODE catalyst system
P0420 - catalyst system efficiency below threshold Bank (1)
After replacing catalyc with aftermarket i got a code in 2 weeks.
i found online that it can be from an exhaust leak!
Today i took care of that and erased the code. i want to see if it will come up again,
Has anyone seen that before?
