When should the MAF sensor be cleaned?

[Flipo]

baka gusto lang nya justify yun cost ng service nya.
sinama ko rin air intake baklasin.

madali lang yung maf sensor bro, unscrew lang then spray ng maf cleaner. contact cleaner nagamit ko ok din. i even used cotton buds with IPA dati, ok din naman, wala naman masyado dumi kaya kahit spray lang ng cleaner. careful lang dun sa sensor probe na hindi magalaw o madamage.

its the throttle body and the intake manifold that i am tempted to clean but hindi kaya ng "baklas-kalikot skills" ko kahit may tools ako[emoji2960][emoji16] may mga sensors na nakakabit mahirap na. egr kaya ko, ako naglilinis dati. wala na gunk since naka blanking kaya di ko na binubuksan[emoji846]

On the MAF just spray contact cleaner and may nabasa ako na huwag hawakan dahil nga sensitive ito.
