I just stopped at auto zone to have my check engine light code read.
He says its code 420 and it looks like I need a new cat.
He asked me if I drive the highway allot. Most of my travel is highway.
I've never heard that highway driving is bad for the cat???
Is he correct?
I'm going to look up the 420 code online now...
Oh yeh, 98 Accord coupe V6 auto 110,000 miles
