Is it plugs, cop, 02 sensors or something else.

 

Do you mean P0420 and P0430? Bad cats.

 

 

The codes you posted are non-nonsensical. Please clarify what the full and complete codes are so we do not have to guess or try and fill in the blanks.

 

 

The code reader I use is a basic one. All it says is the following 2 codes:
P0430 and P0430 P

 

That's low catalyst efficiency bank 2 (driver's side) both a pending and a hard code. Change the rest of the plugs, clear the codes, and see if they come back.

If you have driven it much with a miss, that can trash the cats. Low efficiency isn't necessarily harmful unless they are getting plugged, but you won't pass an emission test without fixing it.

 

 

UPDATE!!! Codes came back. Still getting P0430 and P0430 P.
Is it one of the COP or is it really the 02 sensor and Cat?

 

Well, it probably started out as just a misfire but now the cat is toast. May have left the original problem unrepaired for too long thus ruining the converter.

 

Do you know the correct catalytic converters I should get. I just did a google search and there are a bunch out there. Some as low as $36.

Not sure which one to get that will not throw codes.

 

Are you in California?

Do you have to get emissions testing done as a condition of registration or plate renewal?

 

 

Then feel free to either ignore the error or, otherwise, install anti-foulers to fool the system into thinking the cat is working and to keep the MIL off.
