Hi,
Recently I was surfing around the net and found an article talking about how in March of 2003 Honda extended the Emissions Warranty on 1997 accord because the EPA found out they had de-sensitized the knock sensors...I think the warranty was extended for 15yr/150,000 miles(punishment from the EPA).

Anyone have any info on this? I cant find the site I was on when I read that, however if you look here
Under Service Bullitins, the third one down says
98-081 MAR 03 Emissions System - Warranty Extension

I have a 1997 accord and so this interested me very much, any info is appreciated...
