I have had a trouble with my new g16b conversion in my 92 sierra every time I reach highway speeds. After sitting on 90-100kmh for roughly half a hour or more my check engine turns on and flashes code 13 (bridging the diagnostic plug) My understanding is that is O2 sensor, but if I turn the car off and back on its clear. The light does not come on around town or 4wding only highways. What could be causing this? A bit more information, it's a g16b from a vitara (distributor) and the O2 sensor is a single wire type. It has jimmy g13b extractors to a 2 1/4 exhaust |

It normally takes some time for the o2 sensor error to appear, as the Ecu only refers to it once the engine is warm and cruising. |

Check you engine and O2 sensor grounding and make sure there isn't any exhaust leaks upstream of the sensor |
