Sorry for your loss.

A common mistake/misprint/confusion is which table to read, and what letters/numbers you think you are reading from the Peake.

You're reading the wrong table, but for the most part those codes are similar (except for cylinder #s). See the Peake Sticky FAQ.

In general, your Peake is noting a problem on Bank 2. Start with pre-cat O2s, as they are cheap. B2/B3 are generally not in-fact bad cats. Next, consider new MAFS. Check the air filters. You can safely ignore AA until you need to pass some state inspection.

Pretty sure it's the right table.

I have an older Peake when the table was 18. The new one could be 1b, as you say. I just know there's some confusion on the table in the newer Peakes. I do have a D4 in my table 18; it is as Sailor24 has indicated.
