                These are the recommended units and they went in easily and the connectors snapped on without a hitch.These are critical to a Corvette's drivability and should be replaced every 35K miles instead of 50K.

                              A:

                              The symptoms of Faulty oxygen sensor :1). Poor Gas Mileage: Oxygen sensors play a huge role in adjusting a vehicle engine's air/fuel ratio, the combination of gas and air an engine burns to produce power. A faulty oxygen sensor may allow too much fuel to be added to the air/fuel ratio, resulting in poor gas mileage. 2). Increased Vehicle Emissions:Oxygen sensors monitor and adjust an engine's air/fuel mixture to ensure proper engine combustion, vehicle emissions and performance. A bad oxygen sensor can result in poor air/fuel mixtures or lean or rich fuel-injection delivery, all of which can cause improper or inefficient engine combustion and increased vehicle emissions. 3). Rough Engine Idle: A bad oxygen sensor can cause a car's engine to idle in a choppy, rough manner. This is caused by the less-than-optimum engine combustion firings that result in poor engine performance. 4). Engine Missing: If a bad oxygen sensor causes an engine's air/fuel mixture to become too lean or restricted, the explosions within an engine's cylinders (engine combustion) will be altered ie; cause an engine to miss, or misfire. 5). Engine Hesitation: similar to engine missing. However, engine hesitation is experienced only during acceleration, while an engine miss can be experienced both during engine acceleration and idle. A bad oxygen sensor may misread or misinterpret an engine's air/fuel mixture or air/fuel requirements and cause too little or too much air and/or fuel to enter an engine's cylinders, especially during acceleration. This can cause an engine to hesitate, or stumble.
                              For compatibility of this part Bosch Premium Oxygen Sensor, part number 12014 manufactured by Bosch with your vehicle, please provide your vehicle make, model and engine specification.

                              A:

                              No, this part does not fit your 1991 Geo Storm gsi. The oxygen sensor is located in the Catalytic converter. Most late model cars have two sensors. There will be one at the front of the catalytic converter, and one at the rear. You should be able to see wires going to the catalytic converter. In most cases it is recommended that all oxygen sensors be replaced at the same time to prevent incorrect readings to your engine computer and a constant check engine light being on.

                            I have a 1988 Chevy Silverado, 5.7l throttle body injection, and believe I need to replace the O2 Sensor as it seems it is running rich and then lean and I have a smell coming from the catalitic converter. Is this the censor that is at the end of the exhaust manifold just before entering the exhaust pipe? If it is, then I am guessing there are two on my vehicle, is this correct?

                              Your vehicle has four oxygen sensors. Two upstream (before catatlytic converters) and two down downstream (after catalytic converters). This is an upstream sensor.

                              If this is the oxygen meant to fit your vehicle and those headers have the threaded hole to fit a oxygen sensor, then yes, it should work.
