 EZ EFI keeps throwing O2 code
I just finished installing my EZ EFI system. Upon startup during setup i noticed i was getting an error code. It was the o2 sensor. The handheld shows that it is connected but im guessing it doesnt get a reading becuase the numbers next to it are 00 o2. I then checked and had a small leak in the bung where it was welded. So we fixed it and checked for leaks, no leaks. but that didnt change anything. i removed the sensor, checked it and visually it looks ok. put it back and still no response. the car starts up but goes into limp mode because it the AL is not checked so it isnt learning and its definately running a bit rich cause at idle is smokes black.
could it just be a bad sensor??
