Before heading out for a weekend trip, i checked to see what
muight have caused my van to miss a few beats the last time
i took it out 1 block from home.  i let it warm up and then
gave it throttle right at the engine while watching the
tack...it sounded terrible...missing badly at 3000+ RPM when
i leveld it off and was no longer increasing rpms.

fule level was just above the red reserve level.  I decided
to fill up and see if that did anything.  It did...it
completely eliminated the problem...not a single miss on the
300 mile trip.

I assume it's time for a new fuel filter.  Does anybody know
if anything else might  result in the FI not getting
sufficient fuel flow when the fuel level is low?  The van
was level mostly and the level was just above the red
reserve.  When I toook it out on the road, it produced the
same missing.
thanks
