like i said in my previous post, check out all 02 sensors make sure their good, if your still getting the same codes its the catalytic converter....

what i did not mention in my previous posts was what the reason was that my catalytic converter failed... well here it is

a year before the cat went out, i had a buddy of mine do a tune up by replacing the spark plugs... one of the spark plugs was not tightened and it loosened up and started making a air leaking noise that came from the engine... i eventually had a mechanic diagnose and fix the problem, but by that time my cat needed to be replaced... i hope this helps, cuz this problem drove me nuts...

now remember i had all those codes together, i don't know if your just getting the P1093 code... good luck!
