DIY Cleaning MAF Sensor

GGP2JZ · 09-12-2007, 03:41 AM

I forgot to add this step. This step is very important.
Be sure to clean these items too which are on the MAF sensor as well.

I am just about to go and do this right now. Thanks -Brandon

I had a setback with my damn maf bolts. They are stripped and rusted into the housing, so I have some work ahead of me. Any ideas on drilling/using an extractor tool? -Brandon

omg this does great wonders.. my ave mpg was liek 18 now im getting about 20 some.

my car ran like complete ass, threw 5 check engine codes. I cleaned the maf sensor properly the second time and everything went away. My car gets almost 400 miles to the tank and accelerates like a normal is300

i better go ahead and clean my MAF sensor too!!

CRC brand actually has a spray for the MAF, it's labeled MAF cleaner

I've been doing extensive research on this topic, as to blame this for my rich fuel mixture and not passing smog....

There have been multiple threads on clublexus about people cleaning their AFM (air flow meters) not MAF, and destroying them....

I would advise anyone that has done this or thinking about doing this to reconsider.....

I just did this. My car runs better...I think.

fastsmurf04 · 04-18-2009, 08:32 PM

^^i just did this as well. i first off bought the maf cleaner but decided to take it back and get the electronic cleaner. it seems to have helped maybe. aint drove it much to tell a big difference. but we'll see when time and the next gas fill up comes around. good info!

DUSTINBRAY1 · 04-18-2009, 08:51 PM

when you reset the ECU, while the neg batt cable is unplugged, do you have to turn the key in the ignition to the run position and then pump the breaks? or just while its off?

fastsmurf04 · 04-18-2009, 10:25 PM

i left mine off. i never got a cel-knock on wood........

PR Fiebru · 05-29-2009, 11:17 AM

more mpg? I need to do this!!! I also hear the srt intake saves you on some gas . Is that true

PR Fiebru · 07-15-2009, 11:45 PM

I will do this tomorrow. thanks + rep

IS300luver · 07-15-2009, 11:49 PM

I finally ending up having to get a new one...you can get one from O'Reill's for like 75 bucks. -Brandon

I haven't really noticed any difference right off the bat. I just had it serviced a bit by Lexus though, they may have done a cleaning.

I did the throttle cable and accelerator spring delete right before though, and that was a huge difference.
