water proof plug wires

[cweber2]

Anyone know of a way to check if plug wires are good or bad ?

start it cold, and as it idles and warms up, feel the plugs with your hand to make sure they're all warming up at the same rate. if you have a plug that warms up slow or stays cold, you've either got a compression issue or spark issue on that cylinder.

cweber2,

There's another besides what Isaac mentions. If you have a multimeter you can measure resistance directly. If your meter doesn't autorange then set it for Killi-Ohms scale. Without knowing what the value should be you need to compare your wires to a known good wire, whether that's one of the wires in your set or a new wire. Just remember that one wire in the set for the M37 is longer, so it should have a higher resistance. You can calculate the values per foot (inches/12) to make sure the longer wire has the same resistance per foot as the 5 shorter wires.

The old "slide the grounded screwdriver down the wire" trick won't work if the wire is shorting to the shielding, nor will the spray bottle trick.
