now you have more than one o2 sensor. maybe you replaced the wrong one. and the fuel system malfunction is happening because of the first code, so you can disregard that one. you probably replaced the wrong o2, or maybe you didnt use a honda one. get back to us on it. which o2 did you replace where is it located?

could easily be a gasket leak then. if any air is allowed to get in the exhaust then the cel will light up. try to tighten everything up first. i think i might need some help from someone else to figure out how many o2's that you have. im thinking that there are only 2 on in the manifold and one after the cat, but im not sure about it.

a bad injector......hopefully thats an outside chance though. on my car the nuts on the exhaust manifold got loose after a while and needed to be tightened, hopefully thats your problem too.
