Single bank misfires can be a little hard to troubleshoot. Could be lower intake gasket, injector o-rings, o2 sensors, even a bad catalytic converter on one side.
Also I've seen a low idle cause random misfires.
I'd check that the IACV is clean. Also, with ultragauge, what does it show for MPH at idle? I had an idle problem because the ECM thought I was driving down the road at 88mph, while the SLABS (that actually measures the roadspeed and sends it to the other computer and gauge cluster) was showing correct speed.
