Hey Scotty, my oxygen sensors need replacing on my ford ranger. AutoZone guys told me it won't do harm to the engine. I don't have to replace them. I don't need emissions in my area . What should I do?

if it runs fine otherwise, drive it. if they effect the engine adversely, it would run either lean or rich and you'd know something was wrong by higher temps or black smoke out of the exhaust
