Well I got back from my test drive & like I thought the misfire is still there. I have the MSD whatever wires that have a super low impedance (100-150ohms per ft, I got them cuz I figured they had a decent quality plus they looked cool.) But I'm looking for a much higher impedance on the wires?

While your checking the resistance of the wires you can also check the resistance of each of the coils. All three readings should be very close.

I had msd wires for a year. Two of them started to carbon track really bad, effed up two plugs, and made it run like crap.
I bought cheapie 25 dollar ones just to fix it, they lasted quite a while until i changed them to Beldens..

i replaced my spark plugs and it was fine for a little bit but then it did it again, i got readings on the spakr plug wires but i dont know what they should be at, front bank left to right was .7k ohms .9k ohms and 1.2k ohms rear bank was all around 1.2k ohms, is that normal or do i have a problem?

The wires can be a tough thing to test. With merely an ohm test..they could test well...but with 30,000 going through them...it could be a different story. Simplest test for me on plug wires is to wash my engine down. When it'* running and you hose it directly..there should be no change.

Internet...ROFLMAO...thanks man...needed the laugh.
I got the 97..ran great..wires didn't show anything wrong at all... I cleaned it and they were so bad it set a code....New wires and plugs ...never another problem.

Yours is ALWAYS #4. I suspect at this point you have an intermittent break in the center conductor of that wire or a short through (arc) the insulation to ground somewhere.
