What makes u say ur O2 is bad? Also, before replacing it, consider cleaning it with gasoline. Search google. I am about to try it for the first time. But I got the CEL P0420, which indicates trouble in the secondary O2 or the CAT.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
