Symptoms and causes of a bad ignition coil
The first 4 minutes or so of this video is for you DIYers. I will show you how to identify a bad ignition coil with just a simple test light. The rest of this video I will be showing how to ID a bad coil using both primary current and secondary voltage waveforms on a scope. Finally I will show you how to determine what caused the coil to fail as well as how to repair a plug wire that is damaged, when you are in a pinch. For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.

The power balance test is an easy way to verify if each cylinder is firing. If you do not hear a reduction in rpm when disconnecting the coil pack harness connector, then that particular cylinder is not firing. Check the ignition coil and the fuel injector (link below).Testing the ignition coil while the vehicle is off is an additional test to verify if the coil pack is indeed working or needs replacement.
