I'm getting two check engine light codes, the first one is 1106 Mo 10 3-3 Manufacturer Fuel Air Metering. The second is PO 135 Mo 10 2-3 o2 Sensor heater circuit malfunction, bank 1 sensor 1. Could someone please let me know what these codes mean. I have two dead cylinders and I've checked injectors and spark and couldn't find anything wrong. Thank you.
