1) Remove the negative
side battery terminal (the computer will adjust to the increased air flow
when you reboot in this way). You will need to keep it removed for about
2 hours to allow total re-boot of memory.
2) Remove the bolt
holding on the air box , remove the air filter and air box from the car.
Disconnect the MAF sensor connector wire from the top of the MAF.
With the screwdriver loosen the hose clamp holding the MAF, pull the MAF
from the car. You are now holding the complete MAF unit with it's plastic
air box end piece, with screen, in your hands.
3) With the 10mm wrench
remove the 4 nuts holding the end piece and screen onto the MAF, you are
now holding just the MAF unit. (see first picture).
4) Place the special
Torx (Tamper Proof) bit in your screwdriver and remove the two screws holding
down the sensor. CAREFULLY pull up on the sensor housing and remove it
from the MAF, place it somewhere you won't hurt it! You are now holding
the aluminum 80mm MAF base unit.
5) Remove the plate
on the back side of the division that runs the length of the MAF (two Tamper
Proof Torx screws hold it in place) you will no longer need this plate.
6) Bust out the hacksaw
and Dremel tool, basically you want to remove the entire divider that is
running from the sampling tube to the base of the MAF. DO NOT REMOVE THE
SAMPLING TUBE, this is the small tube that runs along the roof inside of
the MAF, the air that flows through this tube is read for temperature variations
by the MAF sensors, you need this tube. everything else goes. You start
by cutting out the largest portion of the divider with the mini hacksaw
that you can. then with Dremel tool and the round cutter bit you grind
away at the remaining aluminum that is leftover. use the other grinding
bits and sandcloth you have to clean up the areas. When you are done, hold
up the MAF in front of your face, all you want to see is that sampling
tube attached to the roof the MAF, NOTHING else should be obstructing the
Go in reverse order and put
the MAF back together again, drop it into your Stang and re-hook the battery.
Take if for a spin, allow the computer to adjust, and you will notice a
seat-of-the pants improvement!
