Hi all,

On the other hand, a lighning bolt is close to a unit impulse.  The fourier
transform shows energy that covers the entire spectrum.  Maybe this ignition
had a vulnerability at a particular frequency.  Power lines dont normally
discharge lightning bolts and one's car may not be as close to the discharge
point if they occasionally did.
