hello just a quick ???? what would happen if you didn't connect one of the 02 sensors.....would this affect the car when it warmed up.....just put a 97 lt1 motor in my 95 Z i swapped opti's to the 95 style but not the timing cover....i took it down the road and as soon as it warmed up it stalled and the tach was bouncing all over the place any help would be appreciated...thanks

 

Without the o2s the computer will see a lean condition and dump in extra fuel I believe.
