YouTube - 02 values
I had a technician at my work give me some pointers.Watch both pcm 02 values to see if they were the same and were pretty close(i have an 02 sim for h02 2) .If they were then the pcm is not at fault.Test voltage at the 02 to see if the 02 is at fault or is really seeing a lean condition.I still have to test voltage.
