now turning attention back towards running well.
After redoing nearly everything the car did start and run and drove but we have a way's to go.
It fires right up and idles well for about 1 minute then starts to stumble and run rough and will die if you let it.
Not sure where to start. TPS may not be adjusted right, would that do it?
Or vacuum leak? I plan on hooking up my fuel filter pressurizer to look for vacuum issues.
Still running without fuel pressure damper (waiting on the jumper line) but that vacuum line is capped at the moment, verified the hook ups are correct as far as the two coming off the throttle plate area, to the temp sensor/switch and charcoal canister and fuel pressure/damper.
Could be a sensor flaking out?
Good start and idle just won't hold it.
Thoughts welcomed as I sift through thousands of posts on several forums.

suspects;
temp sensor
O2 sensor
AFM

Idle faded and she stalled after about 1 minute. Disconnected the O2 sensor and it ran fine. Sounds like that's it. Probably not because it was too easy.

not hearing TPS click going shut, pulled it and re-adjusted
reattached O2 sensor
idled better with or without 02 sensor attached
BUT
power was way down so did O2 sensor anyway; seems better still
