TFI/timing/TPS ?'s

I've missed Stangnet!! Has anybody else's access been down for two days?
Mine was!
Anyway, alot has happened-
1.) Car was driving fine all day (yesterday), truned it off for a min., tried tostart again and died, started,died, wouldn't start, wouldn't start, etc., etc.
No codes came out, 20 min. later tried to start again, fired right up.
I've read that this indicates a bad TFI, so I tried to put on a wells unit today, swapped between the wells and my old one, never got the Wells to wrok so I returned it and am picking up a Motorcraft one tomorrow.
It was 85* yesterday - does this ound like a TFI problem?

2.) Do I have to disconnect the battery after bumping the timing? I disconnected the SPOUT connector and put it around 14*, so disconnect or no disconnect on the battery?

3.) I set my TPS to .90 with the key OFF. I have heard that this can't be done.
OK......
When I tried to set it w/ the key ON, it was going NUTS!
19.65, 11.64, 7.93, 16.53, so on and so forth, jumpin all over the place?
What's the deal? Cars behavior is fine, no stalling, dying surging idle etc...

Any ideas on any of my problems????????

Thanks guys, good to be back!!

TPS: I pierced the green wire w/ the red lead, connected the black to the neg post of the battery.
What else is there??

No offense taken - the meter was in the correct position, but for all I know, the meter could be crap.
I still find it interesting that I could achieve .95v w the key off....
