do i need new cats according to auto tap? if i am getting a code that says my catalytic system low efficiency P0420 bank 1 P0430 bank 2 - does this mean i need new cats? or is there some other probelm i need to address. i am now also getting another code that has to do with the o2 sensor heater- is this a discreet part or part of the o2 sensor? HELP!

Re: do i need new cats according to auto tap? Things that cause those codes:
Misfire,
Damaged catalytic converters - dents, holes, exhaust leak, too hot (headers?)
Damaged O2 sensors - burned wires, wire grounding
After checking for the above, reset the codes and see if they come back.

Re: do i need new cats according to auto tap? by the way, if you have a stock car, cats are part of the emissions system and are backed by a federally mandated extended warranty. They are supposed to go a minimum 60K miles before "going bad." Some emissions system warranties are 70-100K miles. Ask your dealer about that one.
