Clean MAF?
Hey guys I'm about to go back to school that is 400 miles away and I'm looking to get the best gas mileage as possible? Any suggestions, what is the best and safest way to clean your MAF.

Ok story time is over, chances are your SES light is the MAF Performance problem. Basically the Mass Airflow and Dynamic Airflow readings are now beyond the margin of error that is programmed into the computer. But without grabbing the code this is just speculation.

When done properly, cleaning the MAF is a nice preventive maintenance item, especially on vehicles with aftermarket oiled air filters. As mentioned above, any good electronics cleaner will suffice as long as it doesn't leave a residue. I usually just spray it down evenly, and let it air dry or give it a little compressed air at a very, very, low setting (barely hissing out of the nozzle).
And I agree 100% to leave the MAF screen alone! You can clean it, but don't damage or remove it!

You just have to be carfull with it really. I've cleaned mine 4 times now with no issues. I used a brake cleaner twice and contact the other two times.
Make sure it does not leave a residue like stated above. Spray some on something metal, let it dry and see if it leaves anything behind after dying, if so don't use it.
Using compressed air can really F the thing up too, if you do use it make sure the compressor tank is clean (rusty inside the tank) and don't blow it right at the three small wires!! Again like they staed above...low pressure.

ALL 2001 and up Vettes run the same MAFS the 99+ trucks do, except for the 2002-2003 ZO6 LS6, its still the same 85mm MAFS except the screen was deleted, in the 2004 ZO6 LS6 Vtte, the screen returned.
The screen is s flow straightener, the air intakes on the Vettes are pretty straight to begin with. removing the AMFS screen will impriove flow, but you will need to retune for it.
I have a 2001 85mm Vette MAFS with a screen, I will be installing it in my 1997 Vortec 350, I will be rescalling teh MAFS frequency table using my Tunercat OND2 software.
I will be leaving the screen installed, I have heard that you are supposed to remove the MAFS screen for a dry shot though.
I clean my MAFS screen with GM Brake cleaner as it leaves no residue.
peace
