my car is jerking at low rpm and i think its due to dirty MAF sensor... i tried to clean it use wet cloth but its not easy cause the "dust' is very stuborn...(cannot use strenght cause the sensor is very fragile.) anyone have any suggest what kind of chemical to use? I intended to use circuit board cleaner since but not too sure its possible...

Several solvents you can use. Eg. Carb cleaner, brake cleaner, circuit board cleaner also can etc......

 

Yes, you have to be careful with the MAF sensor because its usually a thin film/hot film. It has a small heated wire which its temp will vary with the amount of air flowing past it. If the wire breaks...its going to cost $$$ to replace.

the contact cleaner should be alcohol based and fast evaporating, not oil based.

 

 

yap, my contact cleaner is not oil based... tested it just now and the cleaner doesnt leave oil residue on the tested surface...

I found the best cleaner is Amsoil Power Foam.

Then I finished it off with a electronic no-residue cleaner.

I let the hot wire/film on the maf cool down first.

Then I spray with PF and let it soaked.

After that I followed up with no-residue electronic cleaner.

 

The engine performs very much better after that. [laugh]

 

But I can't guarantee any form of maf cleaning will not damage the maf sensor.
