That might be covered by the emissions warrenty. It depends on the mileage of the vehicle though. what's your mileage? any acura dealer could tell you. Or better yet call acura's customer 800 number and give them your vin and ask how long the cat. is under warrenty for. Emissions related parts are covered for longer then the normal warrenty. I have installed cats on acura's under warrenty at over 100k. Even if it's no longer covered you should ask if they will goodwill it for you. they might pay for the part if you pay labor. labor should be less then an hour,at my dealer that's 90 bucks part is in the 700-900 range.you would be ahead of the game at 90 bucks.
reseting the light isn't going to do shit for you. It came on because the computer sees the cat. isn't working as it should be.
