I wasn't getting proper signal at my harness. So I tapped the wire coming from the ECU in the engine bay AC31 I think and connected it to coil #3 harness pin and problem solved.
Make sure the signal coming from the ECU is solid.
It's the heat soak in the engine bay and from the over pipe combined with real hot weather. Harness going haywire.
Hope this helps.
