I did clean the air flow sensor. I disconnected the harness plugging into the sensor, removed a couple of Marmon clamps and placed the unit in the utility tub. The intake end of the tube was protected by a course plastic mesh of the same material as the tube. Behind this mesh was a fine screen. I sprayed through the screen directly onto the upstream side of the sensor then flipped the tube over and sprayed the backside of the sensor. The unit looked clean even before I began.

Prior to dismantling the air flow sensor from the car I placed the car keys inside the house thus preventing me from starting the car without the sensor harness reconnected. The car doesn't seem to run any smoother. But it was a good experience to clean the sensor. It should be done on a regular basis when the air filter change is due.

The only slight problem I ran into was getting the harness disconnected from the sensor. There is a small tab in the top center of the connector. I pushed down with my thumb as hard as possible with no results. Finally I used a pair of needle nose pliers on the tab and it snapped down allowing the harness to release the sensor.

Thanks everyone for your help and advise.
