The MAF sensor is located on top of the air box, the black plastic box on the right side of the engine. (If you're facing the car.) It is held in place by two little screws and has a wire harness clipped to it. If your check engine light is on and your car hesitates especially when cold, your MAF sensor may very well need a good cleaning. You will do so by using a spray can of break or carb cleaner. On the bottom of the MAF sensor, you will notice a deep hole in the bottom of which are two little wires. You might have to use a flashlight to see them especially if they are actually dirty. Spray some cleaner down that hole until the wires become shiny and, if available, also shoot mildly with compressed air to dry and completely flush out dirt. Reinstall unit and if you notice improvement on performance, you will likely see your check engine light go off in the next drive cycle.
Guys, let me tell you that this worked great. It fixed my problem right away. My car was running bad (like in 3 cylinder's I did this plus removing the negative pole on the battery and it cleared the check engine.
