Last week, the check engine light in my 1998 Toyota 4runner came on. After driving about 115 miles or so, the light randomly turned off. I was a little worried about it so my brother took it to get it checked out. Apparently it was the oxygen sensor.
Next weekend I am going on a small road trip and I will be driving about 800 miles between 3 days. Should I be ok since the light is off? Is the sensor probably broken or was it a temporary thing?
