I have a 2002 Lexus GS300. So i got error code p0172 & p0175. Witch leads to Mass Air Flow Sensor. Can i just use "Mass Air Flow Sensor Cleaner" to clean the sensor. The only reason i ask is cause i think the can may say don't use on Lexus.

 

Doesn't apply to our car, go ahead, I used it and got a better idle, no problems and only takes like 15 mins, I cleaned out the throttle body at the same time

 

Cool thanks will try it tomorrow and I will reply on how it works.

 

HiI know this an old post but could you tell the difference of it helped ?
Thanks

 

I recently cleaned using the spray MAF cleaner for the first time since my car was made (2004 GS430), and immediately noticed a smoother idle with 1-2 mpg increase. It was really dirty and instead of replacing the MAF sensor, tried the spray first and it worked out great.
