ok i just took my 2000 3.8 v6 camaro to advance auto to get it checked bcuz its not running good at all. i can deff tell its lost power. when they hooked they computer to it, it said i had 2 bad 02 sensors, because my cat is gutted, and it said random/mulitple cylinder misfire, that code come up twice, and i just replaced the plugs like a week ago hoping that would fix the problem but it didnt, should i replace the pug wires next? or what should i do?

 

How old are the wires? it's a possibility that it's coil related.

 

Look at the couple threads in the v6 tech area. There are two others recently with the same problem including one i started...

 

Which O2 sensors? Could be those are the cause of your misfire. I realize you said they bad because of no cat, but I would like to know for sure so we can rule them out.
