OK....have had a service engine soon light on in my 99 K1500 Suburban 4x4 for sometime now. Took it to AutoZone to have scanned. They scanned and gave me a code of P0430 and said that could be everything from a catalytic converter to a loose muffler clamp! Lot of good that did! Can anyone narrow that code down more or help my narrow it down?

I guess you have a problem then.
SAE defines it as a bank 2 cat efficiency code. (since it is a P0 code, it is SAE defined ) My Mitchell On Demand defines it as a bank 2 cat efficiency code. AllData at the shop up the street defines it as a bank 2 cat efficiency code. My GM OBD2 factory training manuals define it as a bank 2 efficiency code. My aftermarket OBD2 training manuals define it as a bank 2 cat efficiency code. i-ATN defines it as a bank 2 cat efficiency code Pages and pages of Googling P0430 point it out to be a bank 2 cat efficiency code.
So, 'zactly what blinky doo-dad it telling you it's a cam position sensor code? And while we're at it, what does your blinky doo-dad define a P0420 as?
