What is this? Still trying to find the problem.

At least I'm learning about this poor unfortunate child. I guess that's worth something, and ... eventually... I will get it fixed.
More info, when I first start it and try to give it gas, it misses and sputters. Any load, like backing out and it doesn't want to run. If I take it through a few revs, or let it run for a minute or so, just idling, it will drag down, almost die and then surge back up. It will do this two or three times and then it's ready to go. This takes three or four minutes all together. It seems clearly to be associated with first start up. I didn't notice it so much at warm start before, but it does it at warm now consistently. After this ritual, it runs great.

you know now that i think of it, and im not sure if you looked into this. Neil had posted 2-3 times to peoples bad running cars to check the Idle switch or something like that and he helped 2-3 people in a row... I will try to search what he said for you and post it

Keep those cards and letters coming, it's got to be there somewhere.
Thanks

Also, while you are in there, make sure there is no standing fuel in the lower plenum.

ya sorry rod, it was about the switches for Idle and Wot sticking so they would stay in a idle or WOT position, i guess just make sure your switches are coming free although the arm is releasing

I'm trying to double and triple check everything. Unfortuantely, the only thing I've accomplished so far is to get my keyboard dirty.

Maybe I just need to get a remote starter and start it up and let it run in the parking lot for 5-10 minutes before I'm ready to go. That just seems to be cheating -admitting failure - somehow. I'm not quite ready for that yet.

Rod,
Let's start a checklist.
Is the connection of the notorious green wire good and clean?
Have you cleaned all of your ground contacts, fuses, etc?
Are the contacts at the ignition resistors tight and clean?
Are you getting at least 3 volts at the 15 post of the coil upon initial startup?
Have you checked for a leaking accumulator or checkvalve?
Have you checked for a leaking fuel pressure regulator?
Does the engine running change when you jiggle the ignition switch?
Have you made your weekly sacrifice to the 928 gods?

Most of the fuses are new, and I've carefully cleaned and used Corrosion X on the front two grounds, the under car ground and the trunk ground. I haven't done the two locations under that dash. I guess I need to do those as well.
Ignition resistors? I haven't checked these. Can you give me a location(s)?
Which is the 15 post of the coil (duh, the one with the big 15 on it - 6.9-7.0 volts)
I have checked fuel pressure in general. It starts and runs at 29psi. It will jump to 32psi when I shut it off and hold for about 30 minutes before dropping. Haven't specifically checked regulator.
Jiggling ignition switch has not effect.
Do you mean have I sent money to 928 international on a regular basis, you bet!!!
Please excuse what may be dumb questions, I just have little experience with the 928, but I have shop manuals, parts cd's, and more patience than I thought I would ever have.

Rod,
The resistors are on the panel in front of the left fender well. Two wires on the coil (15 post) will run to the resistors. Make sure those connections are cleaned of corrosion.
Also, have you cleaned the 14 pin connections by the jump post?
