GRAND_LS 4 Posted July 6, 2005 Posted July 6, 2005 Ladies and gents, clean your MAF sensor, the small sensor after the air filter in the intake tube. I cleaned it using a simple $0.99 STP carb cleaner from wal mart, and it made a world of difference. I had noticed over the last few months that I lost some low-end torque, and when the car gets to 3000RPM, you feel the acceleration kick in. It was never like that before, the torque curve was much more even all thought the band (I especially noticed it after getting the LS, since my previous car had weak low end). So one day, after cleaning the gunk on the intake manifold butterfly, I decided to clean my MAF, and the acceleration is great once again. Big difference and it only took me literally 5mins. You must pull it out though, and spray against where the air usually flows into the maf from the right side. You will know what I mean when you have that piece in your hand. Don’t you just love free power? Also, while your at it, you can use the same bottle to clean up your PCV valve. WARNING: Carb cleaner is a POWERFUL desolvent, dont get ANY of it on your paint!! and avoid skin contact. Make sure you store it in a safe place when your done.
lsrxlex Posted July 7, 2005 Posted July 7, 2005 What year is your LS400? Some earlier threads suggested to leave the 1990 LS400 MAF untouched.

SKperformance Posted July 8, 2005 Posted July 8, 2005 CLeaning any part "carefully" is always a good thing to do. MAF's by nature get dirty like an intake or throttle body, they all need periodic cleaning.

I am going to clean my now! ← Spray 99% pure isopropyl alcohol (available at electronic stores) onto the wires to clean and shake dry. Be careful not to use other solvents as they may damage the sensor. I cann't find 99% pure isopropyl alchohol here in Vancouver, I brought some eletric contact cleaner or elecric head cleaner for MAF clearning, but two wires still looks different, one is yellow, the other one is balck or grey, doesn't look like both shine. even though I can feel the significant different after MAF clean. more power and more smooth. Any advice I can make both shine cleaned? I am a little worried for using crab cleaner or Throttle body cleaner on MAF, I am not for sure if both contain lubrication elements inside, if yes that will easly stick dust qiuckly.
