Computer problem
1999 Chevy Suburban V8 Two Wheel Drive Automatic 103xxx miles

Had a low cost reader to pull a code from the computer and it read P0430. What does P0430 mean?

This code is for low flow of the cat on bank 2. Now bank 2 is the right bank or passenger side. This code could be because of the cat or the after cat O2 sensor.
