two O2 sensers
But now I am on page 116 of Ben Watson's book "How to tune and modify". Still, I am not expert but I am learning a lot.
OK here is my first question. A few years ago I had headers installed on my 1988, while the motor was out. Now, I am in the middle of a valve job and I notice my O2 sensor only reads one side of the motor. They plumbed the sensor near the end of a header, there is no Y pipe. Therefore, the two sides do not come together until the catalytic converter, can it work like that.
Should I have a sensor in both headers, how would I wire
