Air/fuel bouncing after JBA HEADER install
Hey guys (and gals)...
I have a 2014 Mustang GT 5.0 that I just installed JBA headers and off road X pipe on. Since the install, and the tune revision, my air/fuel mix is bouncing from 12 to 16. It's constantly oscillating and the faster I go, the faster it goes. My idle is the same way. No codes and no O2 sensor extensions. What is going on? Please help....!
