Hi, I have a 98 honda civic LX model. Last two weeks, the orange check light suddenly went on while I was driving on the highway.
The code was P0420. The mechanics reset the light and asked me to drive for a while to see if there were other codes came up. Three days later, the light came on again. Still, reset and run,3 days later, light pop up again. Mechanics read the data of everything especially the oxygen sensor and cat converter. Everything was fine. I was instructed to keep driving. Then after one week while I was driving on highway again, the light just suddenly WENT OFF automatically!!! How weird! I'd like to ask what possibly happened to my vehicle and what I should do?
