Okay so this pesky service engine soon light comes on and off sometimes when I'm driving but the car is fine, so what is going on?

It doesn't come on everytime I'm driving it but sometimes it does it'll come on and then it'll go off and then if I shut the car off and turn it back on the light will be off and I've only changed my oil like 2,000 miles ago or maybe less than that

The car is a 1992 Buick Century 4-cylinder Iron Duke and it does not have an OBD2 scanner plug-in but it has an OBD1 plug-in so I don't think O'Reilly's or AutoZone would be able to check it seeing it's an older car and also like I said the light comes on but then goes off a few minutes later so there's no telling when it will stay on and how long it will stay on before I can get to a mechanic to check it that is the problem too

That light works on mileage since it was last told the oil had been changed. When you did your oil change did you reset it?  If you don't know how you'll find many guides on line.

Some expensive cars do have a means to analyse the oil and prompt you based on this.  For most, it's just a mileage counter.

The car has many sensors.  It is confused...because its shorts are in a knot..
. Try this.  Stop car. Shut off. Get out and go to gas filler cap and unscrew it off and screw it on again.  Get in car and restart.  I can do this while the light is red. And get back in and started before it turns green.  So it is quick.   That was after I drove my brand new car off the lot and drove 40 miles.  Then the light came on.  I did that once, and it fixed it.  I don't care where the issue was, it never showed again.  It has been "Years".  When my light comes on it is for an oil change interval time.(which is geared more to miles covered changes)  The other fluids I have to check myself at the same time to be sure everything is good.

Take the car in for service.  It's possible the sensor is going bad, which is an easy fix.  Or you could have an intermittent problem that's setting off the sensor, and getting it checked now will save money down the road.
