After reading your post and watching the video I posted above, I decided to head over to Advanced Auto and buy a can of the CRC MAF Sensor cleaner
I removed the plastic engine cover on my 2005 4.0 V-6 Tacoma,Unplugged the MAF Wire Harness Plug from the MAF sensor,Removed 2 small phillips screws,Removed sensor from the Housing,Sprayed the sensor contacts with the crc maf cleaner,Let dry for a few minutes,Sprayed again,Let dry a few minutes and reinstalled the sensor back into the housing.
Make sure you spray up inside the sensor
There are some contacts that are way up inside the sensor
Also spray the contacts that are on the outside of the sensor
Truck idles smoother and quieter
