Seem to have a Cylinder missing I am suspecting a Fuel Injector
But would like to Make sure its not a bad firing order

Firing Order

I think the firing order changed on 5.0Ls at some point, but I don't know exactly when. To be absolutely sure, look on the forward runners of the intake manifold (not the plenum that sticks up, but the manifold between the V of the heads) - it's cast into the aluminum there.
