Hi I have a 2001 Honda accord that has had the check engine light come on 5 times in the past 5 months. First it was a temeperature gauge (had that replaced), next it was an O2 sensor (had that replaced) now I'm getting a P0420 code and the mechanic recommended I replace the cat converter. I said I was going to wait 2 weeks until I took it in for a full maintenance check and he said I'd be fine. He cleared the code, but this morning the check engine light is back on. Should I be concerned, or can I wait a week still?
