5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
I have a 90 lx and the only code I get is a 91 and your seperation codes 10,11 I cant get it to give a 41 and the #19 wire is ok
In your case, the possibility of having that side O2 fubar is there......you could switch O2 sensors from sides and check if a code 91 shows up instead of a 41....if it does, that O2 needs to be replaced.
