I have the same code coming up and the truck is running kinda rough, has a bit of a shake even once it's warmed up.
We are having a heat wave here and it still doesn't run well until it's at normal temp. So I buzz tested the injectors yesterday and got this code.
While the buzz test was running I heard all the injectors fire, does that rule out a stuck or bad injector and pretty much narrow is down to the harness or pigtail?
