Some kind of coil on the ignition wire
Pulled the distributor tonight and found a small coil wrapped around #6 ignition wire. The coil was broken and the wire was hanging from somewhere around the front of the engine. Anyone know what this coil is and does?

Close Jeff, when its working it
triggers one bank of three injectors every other revolution, so its not true sequential injection where each injectors is triggered when that cylinder needs it. Its semi sequential, triggers 3 injectors one revolution then the other 3 the next revolution.. If it fails or goes bad , it reduces the amount injected by each bank by one half and then triggers them every revolution. So you get half as much gas injected, twice as often.

The pulse generator triggers the bank fire function in the DME. When the sensor reports, the injectors fire in two groups of 3. Without the sensor, all injectors fire at one time.
The Motronic 1.3 DME does not have sequential injection.
I've never really been able to tell the difference between mine when it works and when it doesn't.
