I thought about that, but it scares me a bit. When you clamp an 
inductor, the field collapses slower. That's means the injector 
would stay open longer (just like a relay stays latched longer with a 
diode across it, several times longer than normal). I don't know if 
the EFI microprocessor will correct for that or not 

Anyway, the noise is absolutely radiation from injector wiring in the 
Power Stroke Diesels.
