I just happened across this technical bulletin in my Bentley and thought I would pass on the information. I realize this covers two of the DTCs in the "Lunchmeat" post.

<b><big>Condition</big></b>

The following DTCs may be stored:

<b>P0300 (16684)</b> (Random/Multiple Cylinder Misfire Detected)

<b>P0411 (16795)</b> (Sec. Air Inj. (AIR) Sys. Incorrect Flow Detected)

<b>P1128 (17536)</b> (Long Term Fuel Trim mult., Bank 1 System too Lean)

<b>P1130 (17538)</b> (Long Term Fuel Trim mult., Bank 2. System too Lean)

<b>P1411 (17819)</b> (Sec. Air Inj. Sys. Bank 2 Flow too Low)

<b>P1423 (17831)</b> (Sec. Air Inj. Sys. Bank 1 Flow too Low)


<b><big> Technical Background</big></b>

May be caused by a cracked or broken (braided cloth-covered) vacuum hose to the Secondary Air Injection Combi-Valve.

Most common DTCs associated with broken or cracked vacuum hoses are <b>P0300</b>, <b>P0411</b>, <b>P1128</b>, <b>P1130</b>, <b>P1411</b>, and <b>P1423</b>.

IIRC if you see mult in the codes, its a strong indicator that the MAF is dead or dying
