I should know sooner if the problem persists.

Last night I got caught in creeping traffic and was amazed at how smooth the car ran in 1st gear, creeping along, under 5mph at 800 RPM- didn't need to use the clutch at all, as long as the car in front didn't come to a dead stop.

I might have fixed the problem "temporarily" just by jostling things around. In that case, it will probably show up again, likely at the most inconvenient time.

The range that it can correct if fairly narrow, it can't work miracles in fuel systems control... So anyway that code comes up if for some reason its gone lean or rich outside of the range of control, which would indicate a fairly good sized vacum leak or its running rich outside the range of control, a bad diaphragm on the fuel pressure regulator allowing fuel to be sucked into the intake manifold through the vacum line going to the fuel pressure regulator. I doubt that the gook on your dipstick orings was enough to trigger this code...
To clear the code you can do the stomp test and read the codes then after the codes are done flashing hold the gas pedal to the floor for 10 seconds or so. then shut the key off and repeat the stomp test to see if it cleared the code, if not you can try again. On some cars that won't work so then you have the option of disconnecting the battery for a couple of minutes or waiting until after you have done 60 starts on the car and it will clear itself as long as the original cause of the code has been fixed... So if you start the car 3 times a day thats 20 days and the code clears itself if the problem has been fixed.
