Hi. Have an 02 Civic EX. Engine light has been on for over a year, runs just fine. Reading misfires on 3 cyl, and cat code.
I have since: changed all plugs and coils, changed both front and rear o2 sensors…switched coils around to see if code misfires changed (yes).
I see this is a common problem but no one has a solution…wondering if anyone came up with one yet?
I’d rather NOT change the cat converter and pay for that only to find out the light stays on. Need to smog so I can sell!
