What's wrong with this '95 Ford econoline

Idles rough, seems to drive OK down the road for 30 miles then stalls at a stop sign, and then cranks hard as if the battery is low. But the battery has a charge and the headlights are bright. Once cool, it starts again fine. I've replaced or bench tested almost all the usual suspects. (Including the infamous ICM, aware of the "parts number mixup"). My current list of suspects:

1.) The 175 psi cylinder compression is typical for so old a vehicle but out of spec for ethanol gasoline.

2.) The fuel pump is overpressurizing at idle and opening a pressure relief valve, causing stumbling.

3.) The replaced coil is a piece of junk and I need to get a more expensive one if I expect it to work.

4.) Can the inertia switch do this, the thing you unplug to depressurize the fuel system?

Why do production model automobiles never look as good as the concept models?

You people at Generous Motors and Ford Motor Company have a bad habit of showing us your beautiful concept designs that everyone including myself drool over and then tell us that this is what a certain vehicle you will be building will look like but, LOW AND BEHOLD! When it comes out as the production model it looks not quite or nothing at all like the concept. WHY DOES THAT ALWAYS HAPPEN?(lets use one of the many examples: the Pontiac G6 for example… Only the front grill looks like the concept) Hey! You built that concept the way it looks there, so build about 300,000 more of those identically! What's wrong with that? I'm sick of being disappointed when the actual production model comes out… This happens every year! Chrysler has a better record of putting cars on the road as they looked as when they were concepts. Why can't GM and FORD do the same? Will someone please explain this strange phenomenon. I NEED TO KNOW!

ENGINE OIL TURNS BLACK QUICK? - 1

Just bought a 2014 VW jetta 1.8t, They changed up the oil before me purchasing it. So they did it and a few days later i check it and its back to black. I had a ford and the oil always kept its color and eventually turns brown or amber during age but this engine just turns in dark quick. Is this a problem? What should i do?
