Cleaning the MAF sensor on my LS430

Maybe it's me, where is the MAF in my car ? I would like to try this as my car is not running as good as it used to and the symtoms show what my car has been doing. I have never done this before.
Anyone have a diagram or picture where it's located in my car ? It sounds simple, remove from car, spray with cleaner till it's clean, reinstall, Pull battery for 10 min, start car...

If so, I will do it on my car (2001 LS430) and my wife's car (2000 RX300).

So I grabbed a can and tried it out. I disconnected the battery, pulled the MAF, soaked it and after it dried, soaked it again. I let it fully dry off (let it sit for about 10 min after last spraying), then put it in, then reconnected the battery.
To note, it was black, the whole thing, after spraying you could see the color on it, it was a big change. My LS is sitting at 170K on it now and as far as I know (unless someone did it with out telling me during service). It has never been done.
So, I took it for a ride, maybe about 7-10 miles, When I started it up, it does idle a LOT better, it was always around 1200-1500 RPM, now it idles around 500-700 rpm. It seems to be smoother to drive and no bucking (that is a new problem) when I punched it. I honestly cant give a 100% till I drive it for a few days but, from what I saw, it made a MAJOR difference.
I also did my wife's car too, it was just as bad. If it helps with the MPG, it would be great !
Thanks for the tip !!!!

Hello Lav, there is no harm to the LS430 MAF sensor using this product (CRC), despite warning on can "DO NOT use on ... most Lexus vehicles"?

Thank you, Lav. My '01 has never had the MAF sensor cleaned - 240K+ miles, gets 25 mpg at 79 mph with A/C off. (Plugs and oxygen sensors only were replaced at about 125K miles.) I regularly replace air filter, but have never cleaned the MAF sensor. Should I leave well-enough alone? (i.e. don't "fix" it if it ain't broke.) Thanks.
