Okay, it is late and I've been on the road all day. I will caveat my question with the fact that I have pulled a search and I'm sure the problem is the O2 sensor, but I'm just too tired to remember how to determine the Problem Code.
Okay, it is a 95 FZJ80 with 190,988 miles. It was a mild day today in the mid 80s and I was on my way back to Fort Collins from Denver. I normally fill up with gas at Shell (only because of location to my work and home), but while in Denver I ended up filling up a full tank of gas at a Phillips 66 (I think).
Anyway, about ten minutes from the gas station, the check engine light came on. I pulled over, checked the oil and temperature - everything fine. My first impression was that this was a dummy light triggered by the fact that I went over 190K miles and it might be a 'special' maintanence interval. Believe it or not, my 1987 Nissan Sentra did this at 60K back in 1991 when I was in college. Anyway, I drove it for another 70 miles observing oil pressure and temp and listening carefully - nothing.
In the end, after a quick search of the IH8Mud collective mind, I bet it is a O2 Sensor. If it is, then I'll continue to drive it until I get time to have it replaced.
HOWEVER - if someone chimes in and tells me that I should be concerned and take it do the dealership the first chance I get, then I will.
So please, let me know if my suspicions are correct.
