I believe the MAF housing is part of the entire airbox on the 98-98 trucks. Try www.nix99.com for parts.

Good luck

the MAF housing on the 99-2002 is kind of permanently attached to the air box. But the 96-98 I believe is attached by a few bolts that are removable, because I have a 96-98 k&N air charger kit, but there no place for the MAF housing on the provided air hose, and the instructions say to take the housing on the box right now and use it. Thanks for the reply I'll check out that website.

I could also see stuff lining the walls of the main intake (looking through the TB).

Any way to clean this? Can you spray this stuff in your engine while it's running? i.e. cleans as it passes through?

Thanks!

Amsoil sells an engine cleaning foamin an aerosol can that you spray through the MAF, I used it about 3 month ago and it cleaned up the MAF quite well.

Now that I am thinking about it, you are right. You have to use parts from the existing MAF and attach that to the FIPK for those years. You don't have the original airbox on the truck already?

How do you clean the MAF?

1999 4Runner SR-5 3.4L V-6
How involved is cleaning the MAF? Is there a step by step system I should use. Can it get damaged through cleaning?

I must have missed this before.
Next time someone does their MAS and TB, take some 640x480 pics and do a detailed write-up, and it can go in the Tech section.

All I need is the pics from you, and the text for each picture/process, and it can be put up on the server here.

Holy Cow! It has taken a long time to figure this out. All 2nd Gen's came from Japan with a dirty MAF. I was going to add a TRD sticker for 5 RWHP, but I'll just clean my MAF!!

If I remember correctly on my friend's 22re the MAF was a flapper type so there was nothing to clean and it would not benefit you.

Ok, first off, remember that unless it's dirty, this probably won't make any difference.

I took the air box out (made it easier to get to the MAF). Three bolts, loosen the screw holding the intake tube, and take off the other small hose (leads to the canister or something?) and you're there.

Unplug the MAF, remove two screws and the MAF assy pulls out.

NOTE: I noticed on my that sand/dirt was leaking in around the o'ring. I used some o-ring lube to help this seal when I put it back in.

Take a look at the electrical component that has two flat metal posts and a ball of resin on top of it. If it's like mine, it will look like a black, dusty, carbon covered mess.

Take it into the kitchen (tell you wife you think they are having a sale at Macy's, so she'll be out of the house and won't see you cleaning car parts in the sink).

Carefully wash off the assembly with warm soapy water. I don't know if it matters, but I tried not to get any water on the plug. I also used a detailing brush and gently brushed off the dirt.

I also tried to clean the two smaller electronic components down inside one of the channels, but I don't think it would have mattered either way.

When it's clean, it'll look like a brownish/ orange resin supported by two silver flat metal bars.

Rinse and let dry completely and reinstall.

Tadaahhhhh!

Hope this comes in handy for someone!

Mike

Man, please do not use soap and water on the MAF sensor. If water gets inside of the electronics part it will be ruined. Very bad idea, very bad.

The normal way is to use none residue electronic parts cleaner in an areosol can. Just spray off the crud let it dry off on its own, don't even touch it with anything. If you damage the sensor wires it is ruined also.

Soap & Water, and a scurb brush to boot, you are one lucky guy for sure...

For several decades I poured various (carb cleaner, auto trans fluid, etc.) down the throat of various 2 or 4 bbl carbs to clean the top end, valves etc. It worked. So I am not surprised at what MEMPHIS4X4 advised us of in his post here. Cheers...
