Spark Plug wires

hey guys, I’m suffering from a strange miss fire that comes especially when the car is fully loaded with passengers! I changed spark plugs but that didn’t help much.

Anyhow, I measured the resistance of the wires and it is as follows:
Wire 1 - 12.7 K OHms
Wire 2 - 10.34 K Ohms
Wire 3 - 9.46 K Ohms
Wire 4 - 6.85 K ohms

Do these figures make any sense???

That looks pretty high but consistent. Those must be stock wires and i’m assuming that the wires with the lower resistances are the shorter wires. The resistance should increase with wire length.

well, yeah, in the sense they are consisten… they are stock wires, true… Does anyone has measurments of his so we can compare? If the number is too high then I’m having a miss fire (I think so)…
