More news, was not the gasket issue. Plugs looked okay. I pulled 1, 2, and 4. Played around with wires and double checked everything is plugged in and looks correct. Drove horrible and barely made it out of the drive so didn't try to push it. It'd bog down and almost die and then letting it idle it started doing the same. Did data logging with dash commander and misfire on 1,3,4,5,6,7 shown. CMP is at 2.5. long term fuel trim is bank 1 @ 7.8% and bank 2 @ 23.4%. map reading was steady within 1 kPa at idle. Maf was reading .9lb/min and did fluctuate with throttle.
