Hello everyone. New to the forum.
I have a 1996 Mustang GT that had stored 2 DTCs. P0151 and P1151. I replaced the Bank 2 forward O2 Sensor and the P0151 code is no longer being set. However, the PCM still sets the P1151. Additionally, the Autotap PCM interface I use shows that the last time the P1151 was set I was going approx 50mph and the STFT was a -77%.
My interpretation of that is an over rich condition and the PCM is in a state of asking for much less fuel from the Bank 2 injectors. AM I'm correct? If so at least one injector is likely leaky. How do I figure out which injector?
All comments welcome. I'm not all that experienced with EFI either, so my interpretation may be incorrect. I can accept that..:-)
