Not Really Sure What Else
93 w/126 in decent shape!
At a stop she wouldnt idle and sometimes shuts off.
maintance done: complete distrubtor, plugs, wires, fuel pump, seaform, cleaned throttle body, oil, air filter, shop injector service.
Now she runs ALOT more peppier and strong BUT now @ a stop the idle would still drop but NOT shut off.
Idle @ constant is 750 but drops under 500, then it'll come back up then dances up and down.
Im leaning to a new CPS, TPS also upgrading to Neon injectors..
I just want this thing to run smoothly.
Am i on the right track? Any ideas?

You're on the right track. Before replacing the TPS, there's a way to test it to see if it is working properly. I don't have that information saved so do a search for it! You could save yourself $50. The upstream o2 sensor could also be suspect
