Chuck,
It wouldn't hurt to check/clean all the grounds between the engine and the
chassis. I have also found poor electrical connection between the alternator
body and the engine.

both a Bosch OEM sensor and a generic Bosch cut-and-splice 1-wire.  The
readings have been generally high (I think due to other issues) and the
engine bogs terribly on acceleration while the readings suddenly go
negative!?!  Pushing the pedal down far enough to activate the full throttle
TPS gets it rolling okay and the readings (while still a bit high) go back
to bouncing around in the positive range.  I'm not an electronics whiz but I
suspect the only way this could happen is a short between the wire and the
shielding.
