James: (You're saying check the coilpack connections on the entire engine harness that I removed?)
No more so the coilpack terminals on the coilpacks removed!

James, The fuel pump fuse under the dash was the one I was referring to. It seemed to be sensitive to the slightest play. Just make sure the terminals are sqeezed together well and making good contact with the fuse prongs.

I'm not sure about all of the details since a shop did the swap (I was worried about find ve parts, so I have 2-3 sets of a lot of stuff since my '93 has constant electrical problems). During the first few tests, the car showed good readings (we were using my VE as a benchmark) and everything turned out fine. All the wiring and stuff was spliced and they seem to be a professionally done job, but I'm not sure where the problems are coming from, so I decided to take a look here since it has the same issues as yours minus the stalling.

isolate it to fuel, air or ignition....

I chased a rough running issue which came out of nowhere. By pulling ignition leads I found that cylinder 4 wasn't firing. Spark was OK so I suspected injector. Resistance good I though maybe faulty harness. About to pull my hair out I started fiddling with fuses under dash and found a partially dislodged "Eng Cont" fuse. Pushing it in solved the prob. There were no error codes and pulling the fuse just stopped all action. I was unable to reproduce this behaviour! The only other issue I had years ago was an intermittent MAF Meter issue which was also hard to diagnose. Car is getting to 30 years old. When all is well (which is most of the time) it goes like new. I find the worst problems come from frail rubber & plastic bits which is a worry because there is a lot of that in the Max. The other problem is with capacitors in the electronics. In the end we might all have to revert to cars made from metal, like early Volvos or Datsuns. Or become wealthy and join the trow-away society.

No I still haven't figured it out. I also haven't messed with it much lately though. Constantly running into a brick wall over and over with it gets demoralizing and makes me lose motivation in it. It's so intermittent and random that it makes it very difficult to diagnose. I've only been driving it in spot duty the past few months and it has largely behaved. But then again I only drive it on short trips about 5-6 mile intervals so it doesn't have the time to act up for the most part.

Next on my mental list was to swap the IACV. Too lazy to do that at the moment though.

Did this ever get solved? There was some serious troubleshooting going on here! To me it sounds like something related to heat soak that's affecting the whole engine versus an isolated cylinder. Do VEs have crank sensors, and if so, have you replaced yours? Have you ever done a legit smoke test to check for vacuum leaks?
