Throwing lots of codes

Here's the Codes my FIXD app has shown in the last 500 miles. Is the P2443 code relevant to the Secondary Air Injection System (SAIS)? All the misfires have been on 2,4,6,8 bank 2 side.

The last 500 miles of our 1200 mile trip back from Colorado last weekend the truck started running rough and throwing codes. Some kind of limp mode I guess slowing down to 30 MPH on some hills. The truck has 126,308 miles, new spark plugs in July at 120K miles. I've also replaced the MAS.

Often backfiring, and the last 300 miles or so the ABS system shut down too.

C1201 Engine Control System ABS, etc
PO101 Mass Air Flow Circuit
PO300 Random Cyl Misfire
PO302 Cyl 2 misfire
PO304 Cyl 4 misfire
PO306 Cyl 6 misfire
PO308 Cyl 8 misfire
PO430 Catalyst System Bank 2
B1242 Air Flow Recirculation Door
PO113 Intake Air Temp Circuit
PO102 Mass Or volume Air Flow
P1604 Startability Malfunction
P2443 Secondary Air Inj Switching Valve Stuck

Do you think the problem is the injectors? Also any recomended mechanics in the San Antonio, TX area?
