I tweaked mine once as the emissions test showed higher than it was previously, still in spec but had crept up.
Think I made a note of how much I moved it.

The engine management light should go out when the problem has cleared, and I believe the code clears after 20 non fault ignition cycles if that makes sense. I suspect that if your engine does have this potentiometer then it sounds like it could be your problem, unfortunately I don't know what it is or looks like but I suspect it will have at least 3 wires going to it and if it is just a potentiometer then you should be able to test it with a multimeter using the ohms range.
