OK, I don't have the factory the service manual for this beast (yet), but
I'm looking for some gas savings in it for the wife's sake....

Background:  I have a scan-tool, which I have used to take some readings of
the sensors in two different vehicles, '94 Eagle Vision (3.3L V6) and the
above stated '91 Dodge Caravan (3.3L V6).

Facts:  Sensor readings for the Injector Pulse Width in my Eagle (I have two
readings, one for each bank) indicate that at idle it is 0.8 to 0.9 ms on
both banks...  The Caravan, only provides one reading, so I presume it's for
all injectors (it only have on O2 sensor I believe), gives me am insane (so
it seems) reading of a pulse width of 2.7 to 2.9 ms at idle.

Question(s):    Is this normal?  I doesn't seem like it.  Seems extremely
excessive to me, though it may be higher due to the single bank, instead of
dual?  They are both 3.3L V6's, though I know that doesn't necessarily mean
anything...  I would have thought that they would similar.

There were two codes set, can't recall one at the moment, but that other was
AIS, shorted or (something).  I have since cleared the codes, and no new
codes have been set.  According the scan tool, the AIS is working (moving),
though it seems a little sluggish (takes a few seconds before it moves from
high step number down to a lower number).  I removed it and cleaned it up.
Cleaned up the opening it goes into with some carb cleaner and a wire brush
(at least I think I did, it's in a bad place, hard to see inside).  Van runs
a little smoother at idle, so it must have helped some, but did nothing for
the pulse width at idle...  Tell you the truth, when I give a slight pull on
the throttle and hold it, it seems as if the pulse width actually
_decreases_ despite that fact the engine is running at a higher RPM...

Any advice or information is welcome...
