02 sensor on 99-04 mustang
my car had a dual exhaust when i bought it but since then i had to replace it
with a single which left one 02 sensor hanging. it ran fine for a while but now
my one sensor that is hooked up is bad so when i replace this is the other one
going to effect my car if not hooked up some how?
All your O2 sensors should be hooked up properly or your CEL will be tripped due to the O2 sensor detecting a problem.
