That sounds normal for your model year. The proper amount
should be getting up to the fuel rails. Question now becomes
is the proper amount coming through the injectors.

I tried this scanner many years ago. I often got this message on the
first day and returned it. I think it was because the scanner's connector
that plugs into the Dak's data line connector is really poorly made
(poor manufacturing quality control). I went to a high-end (read expensive)
scanner and had no problems.
It could be, for whatever reason, that the timing is out of whack but I
would have expected that there would be noises (misfiring, etc.).
Do you have a reading for the tps, the pulsewidth of the injectors and
the MAP sensor at and just after 800 rpms? Is there any smoke coming
out of the exhaust pipe when it is stumbling?
