Thanks Arthur.
And look what I just found, and was about to post, after doing some more reasearch:

The car has a 4K rev limiter for P/N to protect the torque converter from operating at high RPM w/no load. It works by dropping a couple of cylinders. It is over-ridden by a speed senor when the car is moving.
You beat me to it.
Any thoughts on the oil pressure issue?
I plan to do filter and oil this afternoon and see if it persists. The car has been largely undriven since March, which is also when it had its last oil change (still less than 3000 miles since) and I suspect the filter may be mucked up a bit, even though the oil appears to be very clean.
Also, I have noticed that the oil pressure needle, at full, does not enter the white space of the 3-bar line, even though I know it is at max level. (On my previous car, I believe it did enter that space.) Also, on pre-start, before cranking, the needle moves to approx 0.1 or 0.2. I don't see why, since no oil is flowing -- or is that a diagnostic to show that it is working?
As for the CEL, I am new to this car, and that type of diagnosis, and still learning about both. I do have your LED diagram and code lists, however.
The previous owner told me that the Service shop (a really good one) that has maintained the car has not found any emissions-related issues connected to the CEL. That does not mean, of course, that other issues are not causing it.
Before I purchased the car, the shop's owner stated that they could not track down the specific cause. It went away after replacing the wiring harness, but then returned, and he said that codes sometimes refuse to clear.
I trust his knowledge, experience and judgment, however, if the CEL is illuminated, even for a mundane reason, it is like dirt swept under a rug and I cannot sleep soundly, knowing it is there.
I will search Code Tool to learn what to do. Thanks again.
