Can fuel system/fuel injector cleaner cause CEL to come on?
#3
02 Sensor. I believe as the fuel injector cleaner has some chemical in it. My friend ran chevron techron and his cel came on..do do do.. My only guess is it made the car run rich..and tripped the cel for a while. it went away though after resetting it.

I will reset after I do a fill-up and hope for the best.

I reset the light today and it is off...so far.
I tried to read the code and was all confused. It would not flash until I tried to drive (move the car), and it woudl stop when I stopped the car. If I sat, it woudl restart after a while, but I was not really sure what I was looking for. There seemed to be no pattern whatsoever to the flashes.
Anyway, hopefully it was the Techron. I filled up and reset the light and I am "off" so far.
I did the full bottle of Techron on 1/8 tank of gas, and the gas had been in the tank for about 3 months.
