Pull the plugs. The plugs that are gas foulded are the cylinders that have the a problem. Check your oil level also. If it has risen the gas has also thinned the oil. Change once the problem is corrected.
What brand injectors, did you use new o rings during installation and did you lube them prior to the install?

The following was copied from the 2006 service manual
P2196 - O2 Sensor Signal Biased/Stuck Rich - Bank 1, Sensor 1
Description: A heated oxygen sensor (HO2S) indicating rich at the end of a test is trying to correct for an over-lean condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.
Possible Causes: See the possible causes for DTC P2195.
P2195 - O2 Sensor Signal Biased/Stuck Lean - Bank 1, Sensor 1
Description: A heated oxygen sensor (HO2S) indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.
Possible Causes: Electrical:
Short to VPWR in the harness or HO2S
Water in the harness connector
Open/shorted HO2S circuit
Corrosion or incorrect harness connections
Damaged HO2S
Damaged powertrain control module (PCM)
Fuel System:
Excessive fuel pressure
Leaking/contaminated fuel injectors
Leaking fuel pressure regulator
Low fuel pressure or running out of fuel
Vapor recovery system
Induction System:
Air leaks after the mass air flow (MAF) sensor
Vacuum leaks
PCV system
Improperly seated engine oil dipstick
EGR System:
Leaking gasket
Stuck EGR valve
Leaking diaphragm or EVR
Base Engine:
Oil overfill
Camshaft timing
Cylinder compression
Exhaust leaks before or near the HO2S(s)
