I had a scan done at autozone and came up with many trouble codes. So far, I've replace the 2 upstream O2 sensors, the MAF sensor, all 6 plugs and cables, and the coil pack. My truck runs a little better but still no power off the line, yet the idle isn't as rough as it was before the plug changes (misfire on #2) I'm still showing various codes upon a scan. The cats seem OK, no "loose change" rattle upon rubber mallet test. Any idea where I should look next? Thanks.

You need to provide some information to go on. Diagnostic fault codes never say to replace parts or that they're bad. They only indicate the circuit or system that needs further diagnosis, or the unacceptable operating condition. At the very least, you have to list the fault codes. Banging on a catalytic converter is a test for an irritating rattle, nothing else. 99 percent of failures don't involve loose substrate or noises.
