2000 Chevy Astro 6 cyl Two Wheel Drive Manual
The code reader tells me to replace O2 sensor.Q? Does default setting affect mileage significantly. Does gas w/crappy ethonal wear it out sooner or give false readings? [Truck is pre-alcohol use]. Will new sensors correct for ethonal? Are generic replacements equivilent? Should I relpace all at once? Where is best online place to purchase?
what else can you share? Smile. Joe
