Ever since I had a new exhaust system put on my 1989 FJ62 it has idled a bit rough and runs different. I can't qualify different other than at 2300 rpm's it seems to have a small boost in power. For some reason I had always suspected that the two o2 sensors had been placed in the wrong exhaust pipes. I finally checked tonight and it appears that the exhaust pipe for the forward bank of cylinders has the o2 bung and sensor for the rear bank of cylinders and vice-a-versa.
So the $64k question is does anyone know if the computer knows the difference if it is getting front bank info from the rear bank o2 sensor and vice-a-versa? I would think that it would, hence the two different sensors, yet I'm not sure how the computer works.
