Last night out of nowhere my 2004 Jeep Liberty starting running very rough and had no power when depressing the gas pedal. I received the error codes when connected with an ODBII scanner. Any idea on cause and if its a solution I can perform myself? Money is tight with the holidays.

Sounds like a bad coilpack on cylinder #2.

"coil pack" and "ignition coil" the same thing? Looking on RockAuto the coil is different then what I thought a "pack" would be.

Two of the ignition coils had failed. We replaced all of them to be safe because as well as the spark plugs for good measure.
