I believe ~0.040. Need to check that. I haven't done the Spring Maintenance yet (plugs, filter, oil change, etc etc) so it is whatever I ran last fall.
This is one of those "nothing changed, why is it misfiring now" problems..
So far the tally this spring is:
Hunts at idle, from 800-1200 (new as of spring)
Started with Misfire at 15psi (late last fall, just started it 2 weeks
before I put it away), now doing it at 12psi
Keypad cord is bad (unrelated??? I unplugged the keypad from it because it
looked to be adjusting setting via the intermittent connection, like ign
trim +5, etc. )
The only "change" is my Optima redtop died over the winter and I replaced
it.. otherwise, car is identical to how it was parked.
OH, and one other total oddity that has been ongoing for a while.. if I
datalog the car with the laptop on battery, it works. If i plug the laptop
into the Link via Serial and DD adapter in to the cig. liter, the car
stalls out. Weird, eh?? (never buy a car that has been underwater!)

Subject: Fuel pressures
Having terrible misfire at 15 psi and even now at 12psi.. I notice my fuel
pressure at the rail is down 4-5psi from where it was last fall. I was
getting around 58-60, now it's ~54-55... this is with the Pierberg pump
from FM.
What sort of fuel pressures are you folks seeing at 15psi? Is 55 ok, or
should I be looking for a culprit? I'll be changing the fuel filter shortly
and checking the pump for any wiring corrosion but it's just developed
since sitting all winter (it has a few issues since sitting, oddly enough,
this is just one of them).
