    Ok well im having a hard time locating the MAF sensor on my 03 3.4 I've read somewhere that if i have a K&N drop in filter in it the oils could dirty the sensor faster than a normal filter would.

    Does anyone here have a pic of where its located and any tips on what to use and how to clean it? Also i just seafoamed it using the brake booster line and changed out the spark plugs what else should i do while im in there?

    Thanks and i searched but couldn't find anything with the MAF sensor location.

    I lost track thousands of dollars ago.
    Its on the side of the intake tube. Get some MAF sensor cleaner from a auto parts store its about 5 bucks.

    Do NOT use a cotton swap ONLY spray it with maf cleaner. The sensor itself is very fragile! Just spray in and around the sensor let it dry and shake it a little and your golden! :)

    If you're using the right cleaner (JUST for MAF, not a general "electric or sensor" cleaner") it evaporates nearly instantly. You can literally spray a puddle of it and watch it bubble away in a few seconds. So, no real need for shaking it...it's super fragile. Spray the heck out of it. Set it in a safe place for a few minutes, install and you're good to go.

    FWIW, I cleaned mine on my 130k mile '02, which had been throwing O2 sensor codes...sensor was dirty as heck. After cleaning the MAF...no more codes. Strange I know, but changing the actual O2's did nothing to stop the codes, so someone mentioned the MAF. I'm a believer now.
