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.
