I was wondering if anyone knew in plain terms where the Map Sensor is located? I tried to follow the gas line but lose sight of it as it gets into the engine area.

Gas line? No no no it would be connected to a vacuum line. Ok, if you look at your windshield, find the center of it. Right below that under the hood you will see a small rectangular box with a skinny hose and a small electrical harness/plug. Thats your map sensor. Or it could be Under hood, center, rear engine area, mounted on passenger side of rear valve cover depending on what model of 3.1
