2002 Nissan Altima 6 cyl Front Wheel Drive Automatic 112000 miles
Ok about a month ago I went to start my car and the smell of gas was very rich. To the point where I could not drive it because it stalled as soon as I took my foot off of the gas. Well I had the mass air flow meter replaced. A couple of days later my check engine light went on P0420 which means converter is less than threshold. Do you think that the cat convt. Is clogged, or can it just be an o2 sensor, or I do you think im going to need a whole new exhaust system? Please help this is getting very expensive. P.S. I have been using better gas I went from using 87 to 92 since the prices have dropped thinking the car would run better.
have the same problem?
