Does the #8 plug look the same as say #7 ? A partially clogged injector could cause you trouble. Its unlikely to be an ECM problem. They tend to be more consistant when they die. I'd expect the injector to just not fire if it were computer related. It is possible you have a flaky connection in the black and white connectors though. I forget which is which, but one has all the injector wiring in it, the other is basically all sensor inputs. Its probably worth opening those up, cleaning the connections and re-applying some dielectric grease. Carfully spreading the pins a smidge on the male side of the plug may also not be a bad idea, but don't go overboard on it.

Gonna check the salt/pepper shakers sometime in the next couple of days. I did have the fuel pressure checked but I dont necessarily trust the fella who did it I've heard stories from ppl that have had him check things that he never actually checked. Though I had not known about this at the time I had it done so maybe the purchase of said $53 gauge is in my future.

I got mine at Advance for less than that. Harbor Freight also has them fairly cheap, under 20 bucks I think.86 Lincoln Town Car (Galactica).

Well I changed #8 fuel injector last night wasnt bad at all hardest parts was getting the dang fuel rail off those are some damn tight orings. I drove a couple of short 65-70 bursts on the way home and didnt notice anything, but I wont really no till I go on a longer interstate drive (possibly later today). All in all I really think I got it this time. Seems to me that the old one was leaking especially due to the plug being wet and the fact that I didnt have to bleed the fuel system. It just so happened to not have any pressure when I got to pulling the injector about half an hour after shutting off the car. I would honestly think there would have still been fuel pressure after only half an hour.

If one injector was shot, the rest I'd also consider questionable. If you can get a full set of 8 rebuilt and flow matched for a reasonable price, its probably worth doing.
Make sure you lube the O rings when re-assembling. They will tear otherwise. Also be sure you have no fuel leaks before starting the car. I caught my car on fire doing that. No grease + no leak check = one hell of a degreasing, though it cost me a transmission and I had to do a bunch of rewiring.86 Lincoln Town Car (Galactica).

On long interstate uphill grades, the wagon will miss once every now and then. Only on hills. This is a CFI car. I saw this a lot yesterday, in VT on I-89 in the green mountains.
Maybe related: occasional codes 14 and 18. I've hit the distributor contacts with contact cleaner, inspected the wiring, reapplied thermal grease to the TFI, and did the ohmmeter checks on the TFI that the Charles Probst book describes (which checked out OK.) Still get the 14/18 now and then. The motor occasionally stalls from idle when it's partly warmed. I read somewhere that a stall can cause 14/18, so maybe that's all the codes are.
The miss isn't bothering me much, as it only happens on fairly steep grades. That's what lopos do, right? Drive it and enjoy it, right?
