...This happen to you? My car has had the "check engine" light on for about a week so i took it to the dealer and they said that both catylitic converters were gone. On a 2005 vehicle? Is this unheard of? I have the certified Honda warranty plus and additional warranty so it is covered but what the hell? is this something one-off for Honda. It sounds "suspect" to me and i would like to know what everyone elses expierence is. To give a bit of background, I am running full synthetic and have burned a tank or two of premium gas until I realized the mileage is made WORSE (would this have something to do with it?)
