1991 Chevy S10 PU 2wd 2.5L

Samuel Jarvis, the creator of this video, says…
“The vehicle is 1991 Chevy S10 PU 2wd 2.5L E code manual trans, connection is directly at the engine computer to the oxygen sensor signal and ground, no scan data was collected during this capture. The vehicle has an issue of the oxygen sensor signal staying high for a long period of time after a cold start with colder ambient air temperatures. Sometimes a code 45 rich exhaust will be present but the MIL has not been illuminated the bulb lights key on engine off. A PicoScope 3223 using the new beta version 6 software with a notebook computer was used to capture the presented images.”
