PCM code help
Ok..need a little help...got a "C" code "10 PCM 1 code" in the DTC;(P0430 H C)...I've learned that it's Powertrain Control Module and it's meaning is {System Low Efficiency Bank 2-A}....Check Engine Light is on obviously which prompted all of this, however, I have not noticed anything wrong or different about the car (2000 Non-Z with 39K).
All the other codes (there were several under different modules) but they were all H...the above listed code was the only one with a "C" after it which I understand to be "current". I reset all codes to show "no codes"..but the check engine light came back on after about 10 minutes of driving.
Could this be Cat related...exhaust has been a little smelly lately..have had Melrose headers on for a few months...Corvette Dr. said I may get a code at some point...he said he didnt need to tune it after install since they're Melrose and not LG's.
I read this site: http://www.gearchatter.com/viewpost14093.php but it doesn't really help me determine if something is wrong..will it go away after so many ignition cycles?
..any ideas would be greatly appreciated....thanks..Paully.

First, you might get better response if you post this on tech section.
The P0430 means the bank 2 cat is ineffient. If you don't find any leaks, replace the cat converter.

Yea I reset it again and it's been gone for a day. It's gotta be related to the new cats/headers I got 4 months ago...I just didnt think it would take this long to throw a code...thnx.

Yup! Mine took a few months for the code to come as well. Sometimes it will stay away for a day or so, etc...
