if you do not drive the car very often, i would start with clearing the code, then go for a short drive and see if you can duplicate the problem. with a car that sits alot, it could very well be moisture or corrosion on the MAF, or any number of things sticking/angry from not being used normally.
i have seen several of these cars randomly go into reduced engine power for no real reason, and its almost always either VERY repeatable, or impossible to duplicate......so the quick test is to clear codes, go for a drive, and if the light stays off, it likely just had a bad morning
