Hey bud, that sounds well off, as my (ignition amplification unit) failed 'ingition trigger/boster' These I belive are only on the AGU engine connected to the airbox & this make it look like a coil back has failed. The garage was stummed at 1st until I pointed this out to them.
The later coil pack have them built in (more prone to fail) AGU coil pack are rock solid
