new cel codes to decipher P0301 p0303 p0304 p0305 p0420 p1300
Just when I thought I had most of it figured out I pull the codes today and I got the P0300 random misfire’s in the
P0301, P0303, P0305
and then P0304 so it’s not just the bank one anymore?
I have cleaned OCV and the vvti solenoids will be replaced tomorrow.
I get these codes too
P0420 catalyst system efficiency below threshold bank 1
P1300 no DTC definition found
P1305 no DTC definition found
P1315 no DTC definition found
P1325 no dtc definition found

Looks like you have plugs and ignition coils to replace. For sake of diagnostic, as it's easy access, move #4 coil to cylinder 2 or 6, and see if code follows.
I'd re scan after you replaced plugs and coils, the rest could easily be aftereffects of bad fuel combustion.
Also, after you replaced parts, pull ECM fuse out for about 15 minutes. It needs to relearn new parts. There's also Toyota drive cycle, won't hurt to do that too.
