I finally replaced my front O2 sensors this past weekend,due to gas mileage dropping. Well,now the gas mileage is worse! And,there is a slight loss of power! I unhooked the battery while replacing them,so the computer should have learned the new sensors by now. I read somewhere else that a person had a loss of power,and had the computer flashed,and that fixed the problem.Any other ideas?
