call a tow truck.

I designed hi-rel computer gear for the military for 20 years and I STILL
don't trust the black boxes either.

That's why I refused to design one that was not completely redundant.  I
haven't had one fail yet but the "fear factor" alone is enough to make this
worth while.

One benefit of the Mazda 2 injector per rotor setup is that I was able to
incorporate a limp home mode in the event of an injector failure.  Using
Mazda injectors I can maintain 75% power when running on just 1 per rotor.
