filthy rich

[Greg Merritt <gregm@umich.edu>]

Hi all,

	my '71 has started running incredibly rich--dumping out smoke.  It
runs rough at idle & cruise, and just *flies* with oodles of power when
accelerating hard.

	I stuck in new points & plugs (had 'em laying around),
*electrically* tested injectors, both temp sensors, throttle position
switch, manifold pressure sensor (resistance only) and the grounds directly
at the huge main plug that connects to the brain; everything a-ok.  The
thing will still idle with the manifold pressure sensor vacuum hose
disconnected--a new one for me (seem to recall that it would die when this
happened in the past!).  I tried swapping with a pressure sensor of unknown
condition--no change.  Ditto with a throttle position sensor that was clean
& tested well electrically; no improvement.

	The cold start injector doesn't seem to be leaking (tested by
running fuel pump w/ engine off; probe [screwdriver] stuck in intake came
out dry).  Also, the problem doesn't seem tied to any one
cylinder--unplugging one injector at a time doesn't draw attention to any
particular one; seems to be across-the-board.  I swapped condensors (with
one I had lying around--condition unconfirmed) with no change; ditto with a
known good brand-new Bosch coil.

	I'm at a loss at this point.  I'd *really* like to get this thing
zooming again so that it will do the snow/salt/ice duty this winter,
instead of the '69 (I know, I know--but we don't have a "real" car, and we
enjoy eating & having a roof over our heads:).  I haven't yet tried
swapping brains (in the *car*, for all of you yahoos!), and I haven't done
any flow testing of the injectors.  Any suggestions would be much
appreciated!!!
