billydpowell Posted December 23, 2011 Posted December 23, 2011 just clean it with carb cleaner and see what happens.. copied from LOC. Sounds like you were just cleaning the air temp. sensor that is built into the MAF sensor. The part of the MAF sensor that needs cleaning are the two small wires inside the tube The MAF sensor is very important to the running of the car as it determines how much air is entering the engine. As the hot wire within the sensor becomes dirty over time the sensor indicates more air is being drawn in than actually is. The ECU, using this data, will start to add more fuel leading to poor idling, poor throttle response, increase in fuel consumption and a reduction in power. I recommend that the sensor is cleaned every 20,000 miles or every 2 years as it is very easy to do.
