I bought a set of brand new GM ZR-1 D545 coils.

So.........More coils, more tests:

Summit/Accels :

Primary / Secondary
1. .7 ohms / 7.02 k-ohms
2. .6 ohms / 7.06 k-ohms
3. .6 ohms / 7.06 k-ohms
4. .7 ohms / 7.00 k-ohms

Brand New GM D545's

1. .5 ohms / 5.71 k-ohms
2. .5 ohms / 5.64 k-ohms
3. .5 ohms / 5.66 k-ohms
4. .5 ohms / 5.66 k-ohms

The one thing I did notice on the Summit Accel coils was that the slots on the bottom of each coil(that the 2 spade terminals plug into) were bigger and more loose than on the GM coils. They definitely don't make a nice tight connection. That may be the problem.

I should have the car back together tomorrow and we'll see if it's fixed.
