[s-cars] Actually the problem is worse than I thought.

Adrian,

I am trying to track down the same boogy.  My stumble/power
loss/misfire is intermittent, occures under light throttle/idle
conditions (for the most part), has stubbornly resisted detection via
the injector connector pulling method.  I have replaced the fuel
filter, the fuel pressure regulator, and am in the process of swapping
a new POS for each of the two existing units.  All for naught, till
perhaps now.

Yesterday, I swapped the new POS for the sencond unit (driver's side).
 I just unplugged the connectors from the existing unit and plugged
them into the new one and zip tied it in place for the test.  The
short test drive I did yesterday did not exhibit bad behavior.  I will
drive it for a longer period today.

Also on the to-do list is a new O2 sensor/connector swap even though
the existing sensor has only about 30K on it.

I'll let the list know how things play out.
