[s-cars] Bullet Dodging 101 - Phew!

[Bob Frizzell]

Bob,
Maybe I missed it but with that key that loose I'm sure you would get the
CEL and the 2113 CPS code under acceleration.  If you didn't then I don't
believe it could have been all that loose before a wrench was put on it.  At
least that was the case with mine.
