I'm guessing at this point, I'll check them for sure.  I believe they are
the ZFR6's also.

Gaps too big on the plugs.

From the FM install directions

Remove the spark plugs and set the gap down to .034” for NAs and .028” for
NBs. Hydra ECUs
enable a larger gap. If the car still misfires, decrease the gap (to a
minimum of .025”) or replace the
wires. We’ve had the best luck with a combination of Magnecor 8.5mm wires
and NGK ZFR6F-11
plugs. Other products - wires in particular - we’ve seen have been much
more likely to misfire.

Subject: RE: Fuel pressures



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).
