The sensor in your Ford Mustang is responsible for monitoring and measuring the amount of air that enters your engine through the intake. The information is sent to and used by your computer to determine the amount of fuel that needs to be released so that proper air/fuel ratio is attained for precision performance. The OE oxygen sensor on your Ford Mustang 1996 is intended to connect to your engine's computer and plug in to your stock wiring harness. This sensor should be equipped with an adapter like a Bosch Oxygen Sensor OE Connector to make sure that your new unit of sensor fits with your old equipment. This connector provides proper fit with your wiring harness, to ensure that your new unit will work properly. Your Mustang should operate at its peak efficiency and reliability level, thus the engine must maintain a very precise air to fuel ratio. The stoicheometric ratio is accurately 14.7 to 1 air to fuel. Such balance is well maintained by effectively measuring the oxygen concentration in your exhaust gases. The measurement is not a problem if you are employing a good-quality oxygen sensor OE connector from Bosch. Your oxygen sensor will surely operate properly if it is hooked in to the system using the right oxygen sensor OE connector. If you have a bad connector, the whole engine system will just fail. In such case, your engine will start stuttering, stalling, or showing drastic decrease in fuel mileage.
