2005 tahoe p0300 HELP!

[Bjsetz89gt]

Hey everyone, I have an 05 tahoe, t vin 5.3 w/o egr system with a p0300. The misfire is happening at idle, then goes away completely over 1200 rpm. Bank 1 is leaning out, and ltft b1 reads high at idle and drops when driving.
Here's my freeze frame:

Fuel Status = 0 byte
Engine Load = 19.608 %
Engine Coolant Temperature = 197.6 °F
Fuel Trim Bank 1 Short Term = 0 %
Fuel Trim Bank 1 Long Term = 12.5 %
Fuel Trim Bank 2 Short Term = 0 %
Fuel Trim Bank 2 Long Term = 8.594 %
Intake Manifold Pressure = 5.221 psi
Engine RPM = 632 rpm
Speed (OBD) = 0 mph
Timing Advance = 17 °
Intake Air Temperature = 96.8 °F
Mass Air Flow Rate = 5.82 g/s
Throttle Position(Manifold) = 12.157 %

Fuel pressure is at 48 key on engine off, and jumps to 58 at idle.
Cleaned maf and throttle body, inspected the bank 1 injectors (clean), vacuum is at 18.7 and I can't find a leak, compression test is good too, lowest was 159, and highest was 166. Been doing all the diag work myself, but I'm not all up on how to interpret it. Could anyone make anything out of this?

Attached misfire data from after I replaced both upstream o2 sensors

P0300 is one of the cylinders misfiring i would throw a set of brand Acdelco Plugs and wireset
