I changed a low beam light on the drivers side yesterday morning, the bulb receptacle looked a little melted/burnt on one side. I plugged in the new bulb and it lit right up. So I figured I would change our the bulb receptacle later. Then I drove it about 13 miles yesterday evening to go to dinner. On the way home I started to smell a burning plastic smell, it was getting stronger, after about 6 miles the check engine light turned on. I stopped, checked under the hood for flames or smoke, and saw nothing but smelled the burnt plastic. The engine light stayed on as I drove home. This morning I went to CarQuest to read the engine code and it came up P0108 MAP/BARO circuit High Input. I reset the code and drove home the engine light stayed off. Then about 20 minutes ago I drove my wife to an appointment and the engine light came back on, I don't know the code yet. But my question is when a MAP sensor goes bad does it burn out and give off a burnt plastic smell? And how can I test to see if it is bad?

Or any other ideas concerning this are welcome, I realize the burned out low beam light just might be a coincidence. The car is a 1996 Bonneville SE with about 178,000 mile on it.

It shouldn't give off any type of smell. Check thoroughly around your engine compartment before continuing to drive the car, something may be touching a manifold, etc and could start a fire, who knows.
