tracking down missfire

[Black'Rado]

Trying to track down a missfire in this truck
99 silverado 5.3l 4x4
we changed coil packs, plugs and wires and still get a miss at idle and under load.
i logged it and shows that cyl 5 is really the worst.

maybe im missing something in the log, but maybe someone could look at the log and maybe can find something.

thanks

Could be an injector (clogged). Good luck
