Part number for Toyota MAF O-ring

[plu]

This is just for reference. I kept getting a P0171, rev hunting when coasting to a stop and a rev drop down to 500 RPM when stopped for longer than 20 sec. so I cleaned the MAF sensor. Reinstalled and the low rev problem was still there. I took out the MAF to spray again when I noticed that the O-ring around the MAF sensor was stretched to the point where I can pull on it and it did not create a good seal. I went to Toyota for a new o-ring and they said that I would have to buy a new MAF sensor for $164. Toyota told me o-ring did not come seperately.

After some research online, I found Toyota part #90099-14141 from JAPAN that should work. I brought it at my local Toyota for $1.29 and it works like a charm.

You should replace your O-ring everytime you take out your MAF sensor to clean or whatever. The cold from the sensor spray kills the o-ring so I would replace it everytime. Hope this info helps someone.
