A few weeks ago I got code P1131 so I changed O2 sensor 1 on bank 1 it didn’t help so I bought a little bit better scanner it is showing almost the same on bank 1and2 so I cleaned the map sensor with the spray that’s for that didn’t help so I changed fuel injectors when I first put it on the scanner bank one was showing 40 so I tapped the valve on the fuel rail and they started reading about the same but still getting same code today I got a Additional code P1043 I read it could be a shorted harness on injector 3 I could use some help please
