O2 sensors are vital car sensors that are designed to monitor the fuelair mix in your vehicles engine. It is possible to fool your cars computer into believing that the catalytic converter is present. I dont know a whole lot about these trucks but there are plenty of S-10 forums that probably. If it just has one and it is a before cat O2 plugged into the exhaust before the cat or right in the begining of the cat plub that bitch back in and leave it.

Symptoms of a Faulty Manifold Pressure Sensor. The transition rate is slowest. Connect the red probe to the o2 sensor signal wire. This constant flip-flopping back and forth of the fuel mixture occurs with different speeds depending on the fuel system.

- 78 wrench or 02 remover wrench. In this video I will show you how and Oxygen Sensor aka air fuel ratio sensor works how the heating element ground power and the signal wire work and a hack. So it goes o2 sensor drilled out non fouler regular non fouler cat. Can you trick an O2 sensor.
