RE:intermittent power loss Update

I am coming  in late on this thread but have you checked to make sure
you are getting full throttle enrichment?

One way to check this (and a good health check in general) is to hook up
a DVM to the O2 sensor and monitor it while you drive around (I think
you car has a O2).  It should oscillate from 0.4-0.5VDdc at idle (0.5
Vdc is ideal mixture) and during light throttle cruising. When the full
throttle switch is closed it should go to about 0.8-0.9 Vdc. This is the
full throttle enrichment.  This could tell you if you power loss is a
lean condition.
