Answers :

Look near your A/C system and under the overflow hose for the coolant. It is a round can looking thing with a small wiring harness attached on top. There rae 3 hex screws holding it on to the bracket. Remove these and slip it off of the air intake tube. Use a small screwdriver to depress the small latch on the inside of the harness and gently pull it off. Disassemble the MAF sensor from the mounting plate, remove it from the vehicle and spray the wires with carburetor cleaner several times. That should clean it up for you. Good luck and let me know if you need more info.
