Description: **SPECIAL THANKS TO INTUBATOR, WHO PROVIDED THE EXCELLENT WRITE-UP BELOW**Mass Air Flow Sensor (MAF) can require cleaning periodically, especially if you use an aftermarket high-flow air filter.1. Remove engine cover.2. Locate the MAF sensor. It is situated in a about a six inch segment of the intake tube (between the air filter housing and the elbow at the throttle body).
There is a wired connector which has a plastic collar that helps to lock it in place. Take a small regular head screw driver and gently work the clip off of the sensor.
A flash light will help, be patient and with some gentle rocking and pulling you will see where to place the screwdriver to release the clip. I actually broke the circular retainer on mine about six months ago and have had no problems with it falling off, there is an o-ring inside that allows it to fit very snugly and securely. 3. Now you will remove the segment of the intake with the MAF connected to it. With the wiring harness clip off, take your flashlight and locate the two metal clips that hold the end of the segment closest to the airfilter housing. You can simply reach down and pop these off with your fingers. Next, if you have the SRP Plenum, loosen the clamp at the throttle body and slide it down the elbow a bit so its out of the way. Take the entire MAF Sensor Assembly segment of the intake out, which includes the elbow and the MAF Housing Assembly, which is still connected to it. This may take a little patience but it should come out pretty easily with some gentle wiggling and coaxing. Important: The end closest to the airbox (where the metal clips are) has a large rubber o-ring which needs to be reused during reinstallation so try not to lose it.
4. Clean the MAF and all intake parts up to and including the elbow, you will find that there is probably quite a bit of oil in all of these intake parts. Remove the short segment on intake that the MAF sits in to clean it separately. Important: USE ONLY MAF CLEANER on the MAF. The rest of the intake parts can be can be cleaned out with carb or brake cleaner. Note: You will see that it is possible to remove the MAF Sensor Assembly from the intake tube without removing all of these intake parts using a special removal driver (In lieu of the special driver, which is hard to come by, one can use a pair of vise-grip needlenose pliers to clamp onto the lip of the screw and remove). Once you've removed these "special" screws, you can replace them with phillips head screws with the same thread pitch and same length for easier removal next time.
The problem is you will have to do it again very soon if you don't get all of the puddled oil out (if you're unfortunate enough to have puddled oil - you may not) as it sits in close proximity to the sensor along the intake tubes anyway. 5. Reinstall everything in the opposite order. The large o-ring previously mentioned should be first reinstalled in the airbox housing end first, not on the MAF segment of the intake.
