The only thing I changed from factory was the T-stat. Distributor looked good when we had it out. We timed it at 0 using the wires under the dash as specified.
Ran perfect for 2 months. 2 years ago I put a new fuel pump. It runs on all 8 cylinders fine especially when moving. I notice it most when parked or at a stop, it just wants to idle erratically. Lurch forward or nearly die. Some days are worse than others. Sometimes if i re-start it after a short drive its is better. Seems to prefer warm days over cold/cool ones.
I have done nothing with the coil ever, I will have to look at that. I figure the coil wouldnt act like this, it would just quit all together?
It almost acts like its about to idle down and die then it reacts and saves itself to just do it over and over again.
Wanted to mention the TPS I replaced twice. The first one didnt work at all. Took it back and exchanged it for another. Wonder if it was made in CHINA and is garbage.
Also when I replaced manifold the gasket kits no longer come with end seals, just silcone. What if the silicone didnt fill in everywhere, could that cause it if it blew out?
I miss the old stuff that was easy to figure out without process of elimination! Id love to rip out the electronic crap and throw on a Holley and a mechanical fuel pump on if that would be easy but Im sure theres a lot more to it than just that.

You need to get the proper 195 stat back in it.
Check fuel pressure for up to specs.
Check for present/stored/history codes and read out sensor data with a engine capable scanner.
And as J-Cat said run a vacumn check hot and cold engine.
Also check engine vacum at idle and at 2K rpm.
Piost back vacumn and fuel pressure readings and amny stiored history or past or present codes and if all sensor reading to computer are good.
