I had the MAP vacuum tube crack on both of our first gen Aveos, and also the sensor itself go bad on the '05 - never any map codes, just running rich like yours appears to be. I'm not saying that's it's definitely your vehicle's issue, just that there is a history related the MAP. And as I said previously, I never like throwing parts, but in this case diagnosing will cost $ to buy a pump and is a bit of a PITA. So that's why I suggest just buying the parts and hanging them on. And if it doesn't fix the problem, I'd cover this part hanging by calling it preventative maintenance
