PLUG WIRES... have resistance? umm...
Ok, I tried to test my plug wires with a multimeter for CONTINUITY. YES I had both ends of the same wire
So i took the wire off of the plug, then off of the coil. Put one end of the meter to the plug end, the other end to the coil end. No continuity. It was this way on ALL 4 wires.
Is there any resistance in the wires so that only high voltage DC can pass through it? I know they are sparking cuz i can pull it off of the coil and see 3" sparks fly to hit the wire .
I also tried and ohm meter but nothing works. It's like they're made out of glass..

Oh forgot to tell for the ohmmeter it was
T1: 12.43 Kohm
T2 : 13.34 Kohm
L1: 17.23 Kohm
L2: 18.02 Kohm
Is it normal for plug wires to have such high resistance??

Oh ya, a quick question, can the engine run well with the leading plugs switched around? meh, just curious

Oh BTW, yes, i checked the FSM and there's supposed to be 16kOhms/meter resistance on the wires so those are fine. But for some reason, my LEADING plugs were switched around and I didnt know it!!!!

The leading plugs are both fired together, twice as often as required. It's called a "wasted spark" set-up and is very common in modern cars. The second "wasted" spark fires during the exhaust stroke, so it has no effect. It means you only need one double-ended coil (and one ignitor) instead of two seperate ones, and it's simpler to control because only one output is required. The same thing can't be done with the trailing plugs because when one is firing the other's actually part way through it's compression stroke. That's why a "pack" consisting of two coils and two ingitors is used.
