your map sensor detects the air pressure inside the intake. this tells the computer how much fuel to squirt. this is a vital sensor. if you are looking under the hood, it is at the very back, on top of the throttle body. grey plug with 3 wires, going to a black sensor with two screws on it. i think it even says map sensor on it?
easy to replace
