Indicates multiple cylinders are misfiring or the ECM cannot identify which cylinder is misfiring.

Possible Causes:
Camshaft position sensor (CMP)
Low fuel (less than 1/8 tank)
Stuck open EGR valve

YMMV
Full tank of gas... how would I test the other two?

Diagnostic, repair, and maintenance info are in the FSMs if you want to DIY. Otherwise it means a trip to the mechanic.

Since you have installed a CAI, I would investigate in that direction first.
