If #5 and #8, together or one at a time, have no affect on engine idle, then it could be an ignition coil, the ignition module or the wiring between the two.



If only 8 has no affect on idle, then it's possible the primary injector at #8 is not pulsing. This could be a faulty injector, the ECM or the wiring in between.
Pulled #8 and #5 at the same time and it idles ruff and sounds the same .
