HEGO is Heated Exhaust Gas Oxygen, in other words your oxygen sensors and yes, a faulty one will most definitely affect performance, you will be running very rich with an inoperative oxygen sensor.

since you are installing the oxygen sensors might as well check/replace the spark plugs you may have fouled a few
