engine light still on.? Had diagnostics re-checked and van rpm needle started to idle up and down consistently until the engine died. Looks like the sensor is trying to adjust the fuel enrichment or something. I unplugged the battery and letting it sit for 10 minutes and hook the battery back up to see if it will reset the system. The van did not have this idling problem until I had it re-diagnosed.
