i met with kennedy (cool guy btw, thanks hoon) and he hooked up the computer thing cuz i had a service engine light. my car threw a code 0420. anyone know what that's all about? apparently it means a 'bank 1 inefficiency' but kennedy told me so many things could cause that code that it would take a whole day to pinpoint the exact cause. may be a bad 02 sensor. i believe him since i had one of those on a pathfinder of mine. anyone else have this problem?
all of my issues, transmission refusing to downshift @wot and marked decrease in fuel economy and now this warning light, have come after a tire blew on the freeway. had to drive for almost a mile to get over to the shoulder and i was going like 80 at the time.

i'm glad you and Kennedy got along great..
well, i guess you can take your car back to the dealer for that..since you don't have any major performance mods(likes of the y-pipes, cat-back exhaust...)...if i recall correctly, you only have the panel filter so far, right?
