service engine light

Hi, My light came on in my 2001 GT, 3.8 about a year ago during a heavy rain. Since then it has been on and off but stays on during periods of moisture. If I let my car sit for a few days, the light turns off and then on again after driving for a while. When scanned the code read a Mass Air Flow sensor. Should I clean the sensor, change the sensor, or is there something else that is causing the sensor to find a problem? The car seems to run just fine with a little hesitation when first taking off. Please help! Thanks.

The maf sensor is easily damaged and if you clean it make sure to use electrical contact cleaner. You can get it at Radio Shack. Spray gently. I would also check the contacts on the top of the sensor as they may be corroded and in need of cleaning. If the sensor cannot be saved purchase a new one not a remanufactured unit as they are not of good quality.
