[s-cars] Stumbling along under load

[Bob Frizzell]

Dave and other terrific S-men,

The more I mess around with this the more optimistic I get that I don't have
to tear the front of the engine off to fix the CPS (but then have you heard
the saying, an optimist is a fool but a pessimist is never disappointed?).
At any rate, how is the CPS connected.  Is the connection under the left
front of the injector cover the CPS connector?  And, if so, where from
there, straight to the ECU?
Even more appreciative,
Bob
