My coil positioning caused my coil to heat up and similar conditions followed. My Accel must not be angled downward on level as it causes the plates to be exposed and they arc and heat up the coil. Similarly I also had issues with the wrong ballast resistor causing the ECU to have problems with RPM's. I have mentioned this before. I use the .25 race resistor when racing and a .8 resistor for the street. Some by-pass the resistor for racing and I have done it in the past. It OK but if you run at idle too long it can cause the coil to heat up and fail. My car would flat die! The 1.5 resistor wouldn't allow RPM's over 5K, maybe less. Just what I found.
