AFM questions
alright guys ive searched and came up with a lot of good information on the AFM. the only thing i dont know is, where is it? is it on top of my MAF? thats the black cover i have to take off right? also i know ill probably figure it out, but once i take the cover off, how do i turn it a few clicks.
i also relize most of you are going to say this isnt a time worthy perfomace upgrade/tuning, but i still want to clean it and everything. thanks for the help.

Should be on top of your air filter housing, if you still have it. You can see mine in the bottom of this pic: http://community.webshots.com/photo/...92263572fKwNmW

While we are on the subject, do NOT ever ever ever for any reason remove those 2 screws near the AFM pin connection. Toyota NEVER should have even put screws there, there is no reason to ever take those out. If you want to unplug the AFM remove the thin wire clip to unplug it, NOT those stupid screws. Ask me how I know, it only takes about 2 hours with a pair of tweezers to resolder the foil strips back onto the circuit board.

Just take a box cutter and cut the sealant all the way around and then pry it off with a screw driver. I don't see any reason to take it off though, I never would have taken mine off if I hadn't ripped the wire connections off the circuit board.

If you do want to remove the 2 screws and pull the whole thing out pop the black plastic cover off first. that way you can disconnect the electrical connections first. the way most people get in trouble is they try to pull it out still connected and wind up using too much force and end up ripping the foil off. With the connections off it slides out pretty easy. you really need the top off so you are not doing it blind. I have taken mine out. I cleaned the contacts with electrical cleaner. I did make the mistake of tring to do this blind at first and it was a major PITA. I couldn't get it back in W/O bending the foils(luckly I hadn't ripped them off) also the fuel relay would go in on the wrong side of the slider arm. I would try to put it back in(blind) and it would start up but only run for a few seconds then die. After a few attempts(and getting really freaked out and pissed) I poped the top off and saw what I was dealing with. cleaned it and put everything back together.runs fine. I had the top off so I decided to adjust the A/F mixture. with the way my truck was running I decided to go 2 notches lean. not only does my truck run better now with more power it also gets better gas milage(up about 3-5 mpg)
sorry for the long reply, just figured I'd post my experience for others. allmost all the replies from searches say just not to pull it, not what to do if you were to of if you had.
P.S. when I sealed it back I used blue electrical rtv silicone. this stuff is made specifically for electrical components and is sensor safe.

OMG mt_goat I did the exact same thing LoL!
I had taken the plug off to move the maf a dozen or more times. That one day I forget to take the wire off on ym car, pull and ZIP! There went the PCB
After melting all the traces off with too hot a gun, it wound up taking several hours, to repair the repairs I was trying to make after doing something stupid in the first place!

BTW we go to Durango, Silverton, Telluride area every summer to wheel the passes. The 3.slow really lives up to it's nick name up there at the top of the Rockys. :cry: Sure would be nice to have forced induction up there.

Sorry for the 20?
Don't really ping,maybe a little on long hauls up steep passes tring to go faster than I should.
I run 87 all the time
I haven't ran It at lower elevations yet. I suspect I will have to readjust I when I move to Ashville this summer. it did come from sea level

hey you guys who did this ripping foil off PCB bit-
any advice on how to fix it, or how much is an aftermarket MAF the whole 9 yards?
thanks

My repair has lasted about 2 years now with no problems. IIRC I soldered one torn foil strip back together in the middle.
