This sensor measures the proportion of oxygen in the exhaust gases. Using this measurement, the engine management computer can adjust the air/fuel ratio near the optimum value of 14.7:1. At this ratio, engine performance, emissions, and fuel economy are all optimized.

Perfect These are the first automotive repair parts I purchased through Amazon. Briefly: they arrived quickly, were packaged nicely, and worked like new when I installed them. I got prices from the dealership and both major auto parts stores I normally shop at. There are two common manufacturers for O2 sensors for my car. These ACDelco are the better ones. The price from Amazon was less than half the cost. Nice. My car has 125k miles on it. The catalytic converters were dead and the o2 sensors…
I would recommend the heated Delco’s to anyone with a trans am/firebird/Camaro These went on my 96 LT1 Camaro with a OBD1 conversion (pre 1996 cars came with OBD1). These really helped my fuel economy and completely stopped my backfire/rich condition. These replaced two Denso O2’s that did not work, I would recommend the heated Delco’s to anyone with a trans am/firebird/Camaro.
