in my tunerpro rt i am datalogging in park and o2 sensor mv are all over bouncing around. Now its not going back in forth between open and closed loop it stays in closed loop
I have heated o2 and there were 2 white wires and black i connected signal wire to black wire

could this be the problem did i hook the o2 wrong or is it because im doing this in park thanks

 

i was reading and i guess thats normal thanks for the thread searches
