Hi iS community,

In order to identify my ignition coil issue, as suggested, I measured the resistance on spark plug caps and it turns out that 7 of them have resistance between 4960-5070 ohm, but 8th one has 5650 ohm. Among those 7, 4 of them have exactly 5000 ohm resistance.

Does anybody know what is acceptable range for spark plug cap resistance and  is it possible that those 650 ohm extra creates issue.
