I have an 88 5.0 Mustang.
I recently converted it to mass air. I pulled some codes and got codes 41 and 91.
so i went ahead and bought new o2 sensors, because i was getting bad gas mileage.
i installed them and i reset the codes. I pulled the codes again and it still gave me codes 41-91.
can the harness be bad?
thanks
