Question Misfires and multiple codes

Replaced VANOS, CVV and 4 hoses, both boots before/after MAF, MAF, O2's, cleaned and sealed DISA, new plugs, swapped coils around, smoke tested and found no leaks.
Not sure what to check next?

Still getting all these codes:
Multiple misfires when starting cold,
P1188 Fuel Control Bank 1 Sensor 1
P1189 Fuel Control Bank 2 Sensor 1
P0170 Fuel Trim Bank 1
P0173 Fuel Trim Bank 2
