Oxygen Sensor location on a 94 Silverado I want to change the oxygen sensor on my 94 Silverado, 2x4, 5.7L. I looked where the ALLDATA diagram shows where it is located but it's not there. Does anyone know where it's located. Am I'm losing it or what? To me this is showing it is on the driver side, on the exhaust manifold. Thanks in advance for any help!
