You'll need someone with more depth than me to give you the best advice, but I'd offer that the FP Relay is a car runs/car doesn't run component. Did the P.O. also operate the car at 6200' elevation? Do you have a fuel pressure gauge you could have hooked up while driving to see if pressure falls at the same time as the stumble you're encountering? That might be a good way to ascertain if this is fuel flow related. I also know from disassembling my car that there is an altitude compensator device under the dash, driver's foot well, near the DME; it'll have a ND/Nippondenso label on it. You could check whether this is plugged in, or not.
Best of luck to you, John

Good taste in cars and model years!
I have a fuel pressure gauge but I don't think it can be stretched into the cockpit of the car. I didn't know there was such a thing.
The car was bought from an owner in Virginia. He never mentioned that it was run at high elevation although I know it crossed the country a few times. He's now dead. Sad story.
I will look for the altitude compensation device.

Checking the cam timing is something I'd do, too.

The emissions report wasn't where I thought it would be but I will look for it.
If by cam timing you mean that the cog was on its mark when the belt was replaced I'm pretty sure it was.
I just drove the car again and something that may or may not be a clue is that if I'm driving steady in third gear and push the go peddle hard it shows good power and acceleration. It does feel like it's missing at other times while accelerating or cruising.
