    Received a code for VNT Veins... found the turbo actuator was leaking air... replaced it and noticed it started saying Low Voltage when I was starting the truck up... now I’m getting a code for : S4 firing order response time short... replaced #4 injector and it’s better but I’m still getting the low voltage and trucks puttin a bit... What do you think?
