MAF Sensor

[NJ H2]

Before you replace the MAF, try cleaning it and throttle body with Carb Cleaner.

Definitely use MAF specific cleaner. I am not sure but I would assume carb cleaner will damage the elements in the MAF.

I am sure carb cleaner would be fine on the throttle body if you had some laying around. But they also sell throttle body specific cleaner as well. A lot of the application specific sprays are based on what film or particles each of the sprays will leave behind.
