Hi Scotty, How do I get my catalyst monitor ready? I've driven 1k+ miles since I replaced the battery. And I've done the 55 mph drive mode also. Every monitor is set except for the catalyst shows incomplete. How is the particular drive cycle like to set the cat? Will it be easier to just buy a new cat? Thank you for any reply.

It's a 2002 Acura RSX Type-S

you need a new cat, period. It's not bad enough to set a code yet, but too far gone to let it pass. BUT , give it one more try, do this video, sometimes it will force it to pass https://www.youtube.com/watch?v=5icTmYItwiE&t=47s

Thank you Scott! I think I will do what you did in the video and give it a one last chance before I replace it. Have a nice day!
