    First: Yes, I searched... and all I could find are threads saying, "clean your MAF"

    Second: I checked the Mods & Tutorials > Improve Gas Mileage and 1st gen how tos and DIYs

    Okay.

    So can someone point me to where the MAF is? A picture would be nice. And can someone (yes, it can be the same person :eek: ) explain, step by step, on how to properly clean it?

    Thanks in advance.

    I no haz photos- but the MAF is usually just to the engine side of the intake filter....near where the filter box becomes a hose or tube.

    They make "MAF Cleaner" in a can that is basically an plastic safe electronics wash...Sprays out and loosens up and blows away anything that might be on the sensor.


    Sorry for the lack of pics...Work computer gives me fits.

    No worries.

    That's a good start. I can at least try to find it and look at it.

    I saw in another thread that it should be orange (if perfectly clean).

    and one other thing, DO NOT AND I REPEAT, DO NOT AND WILL REPEAT AGAIN, USE ANY OTHER CLEANER EXCEPT FOR MASS AIR SENSOR.
    YOU WILL BE BUYING A NEW ONE.
    I had to do this one a year on the stang, because the first mod i did was a K&N filter, (waste of money, and pain in the ass) and any little bit of red oil would build up on the sensor. and their goes the idle!

    This is what it looks like. Spray with MAF cleaner, don't touch it.

    Thanks so much guys, very helpful.

    In that bottom picture, is the MAF those two wires on the bottom below that shaft?

    I have a feeling that this was never done by either of the previous owners of my truck. I will definitely be taking a peek at mine tomorrow.

    Also I'd seen "Check your MAF" In a bunch of threads and also wondered what it was.

    So Madjick_Man thank you for asking the question and thank you to all that responded. You are all teaching me well whether you know it or not!! :D

    I cleaned mine for the first time at 88,000 miles, and it was not really dirty. I had a paper towel under it to catch the drippings from the cleaner, and it did not even stain the towel.

    Some guys say that theirs are really bad when they clean it. I have heard that k&n wet type air filters can cause oil buildup on the sensor, but I don't know for sure if that's true.

    I cleaned mine around 60K miles. Like you, I didn't note anything obvious as having been cleaned. Moreover, I didn't not any difference in mileage or performance.
    I run a "wet" Injen filter, and found zero evidence of oil buildup. I suspect this can happen if you over-oil the filter. Assuming you apply the oil as instructed, I doubt there's a problem. (There wasn't in my case anyway.)

    and while you are in there, its a good time to clean the throttle body, (use the guest toothbrush) and the IAC valve. the engineer who thought up that part should be shot, I dont care what its supposed to do.

    You should take the TB off to clean it. The IAC will get fucked if you don't. I just did all this. Follow the manual, get the gaskets. Pix in my gallery.

    you are right I should have been more clear, and if you have time I would first do a good seafoam treatment, blow the smoke all out and after its cools off, I would do it all step by step.

    If it is at all possible to post pics and simple walkthrough (like post #9) I would really appreciate it.

    Thanks.

    I took pics with the intent of doing a writeup, but just haven't had time yet (I've found that it take a lot of time to do one decently). There are other TB cleaning links, but they dont' go into much detail and dont' show the IAC part of it. I was most interested in the IAC issue, which becomes completely clear once you see how the air flows when the butterfly is closed. I've posted some key pics in my gallery.

    It is pretty simple: remove everything from the airbox to the TB. Four bolts hold the TB on. Disconnect the #3 coil pack connection for clearance to remove. Put the TB on the bench, remove the IAC housing (DO NOT remove the IAC valve form the housing): four phillips head screws hold this to the bottom of the TB.
    Douche the TB with TB cleaner and a toothbrush, and use Q-tips on the airways underneath to and from the IAC. For the IAC, use a Q-tip with TB cleaner on it to gently clean soot and grime from the airways and around the mouth of the inlet to the actual IAC valve. DO NOT get cleaner in the IAC valve.

    You'll need new IAC (rubber) and TB (aluminum crush) gaskets. They are not reusable, and you really dont' want to risk leaks with coolant or fine abrasives in these areas.

    The four TB bolts are 13 lb torque. Do them in a cross pattern.

    I'll post up a few more pictures to my gallery when I get home tonight.
