Cool Cop mod issues

Hello guys.

I did the COP wiring by myself on thursday.The car works and has improved performance.

There is an issue though:Cruising around the highway around 3k-4k rpms with throttle around 5-15% there is a missfire.

With 15-100% throttle NO problems at all plus better performance.

Ripping through gears NOT an issue.

Flatout from 1000-7250rpms not an issue.

The car is a 92 miata with 120k miles and is completely stock.

Thanks for the help and sorry for the missreading of the text and my bad English.

Gapped the plugs 2 hours ago.Because metric fillers i gapped them 0.91mm (.036")

The problem remains plus some occasionaly misfiring around 4k rpm with full throttle.

The capacitor on the wiring is 10000μF 16V.

I need a 12V capacitor?

The capacitor is NOT the problem.

The problem is the bad coils you are using.

You seem so sure about the coils.Have you experienced a problem like this that solved with new coils?

Thanks for replying.

Add more capacitors in series for even better results.
