I replaced a bad Map Sensor. Do I need to reset the computer by unplugging the battery terminals or will the computer automatically relearn everything eventually like proper air/fuel ratio? If it relearns on it's own...how long does it take?

Just drive it.
If you had a vacuum leak before, the car will soon figure out its gone and return to normal.

either way, it will cycle off after a day or more sometimes, or take the battery off for 30 minutes. it will re set the pcm and clear the code.
or if you have a scanner you can clear it that way.

Ok great. I actually replaced it a week ago and the code never came back but was refueling today and started wondering if I should have reset the computer to improve gas mileage.
