PO300 misfire suspect bank 1

Bad misfire PO300. And pO305 a PO306 intermitant after clearing codes. History: 1 yr 3 mon bad front cat bank 2 replaced (DIY). 2 mons ago bad fuel pump. Power prong on pump connector corroded / broke, after repair new pump did not power up. Found short in power wire and cut and splice new wire in. Soldered and heat shrinks. Ran till about 3 weeks ago. Checked spark found bad coil #5, replaced.5 code disappeared. Found damaged 02 sensor, bank 1 replaced. Still Po300. Tested compression, all at 155 to 160 except #2 is 120 dry with oil up to 155 suspect rings. But should still fire. All injectors are clicking. Using PO306 as a clue pulled injector, tested for spray pattern. Good. Replaced bank 1 CamPS since bank one live data seemed way out of normal for fule adjustments. Same issues. I use a harbor freight scanner. So a OEM ENHANCED scan shows stored issues with no code. Shorted CPS, CamPS bank 2, vvt Intake circuit, evt circuit. Intermittently. Also replaced all the air intake gaskets while I had it apart. I also tested TPS per shop manual, tested good. Ohm tested VVT intake bank 1. It was 8.4 should be 7.7. But no shorts. Shouldn't cause misfire at idle should it? Cat on bank one doesn't rattle. And it's only a year or so old. Could it be ECM? Only bank 1 seems to be adjusting around. Bank 2 values hold steady at idle.
