Hi all,

Just wanna share my experience on cleaning waja throttle body. First, I managed to open the black air duct by loosen 1 screw (used no. 11 wrench). Then I twist the black air duct for easy access to the TB. OMG, it was soo dirty on the butterfly plate & sorrounding hole... no wonder my car RPM's goes crazy (RPM went too low & almost stalled)... Then I sprayed some WD40 (as it can remove oil) & wipe all the dirt clean... I notice that most of the dirt were fine particle of dust mixed with some oil.

Be sure to clean the black duct too & the opening of the TB along with the plate. I did not dare to mess the inner side of the TB affraid to touch the sensor inside.

Now the car RPM steady at 850... acceleration is better too. Feels happy again. Car is no more 'tersumbat'.

Pictures.... aiyaa... manyak soriii... my hands already dirty when i should've taken photo. But it's really easy to do, just get the black pipe loose, twist it & take it off, then see the inner side of the TB.... there you should see the butterfly plate all dirty... (after 4 years using the car).... one more thing, when clean the plate twist that black semi semi rounded thing beside the TB, you should get the plate to swivel & clean all sides... need little fingers to do this.

Open the air filter box & remove the hose... clean also the inner side of the hose... spray some WD40 onto the butterfly plate & sorroundings area.... wipe it with clean cloth... twist the black semi rounded thing to open the plate & clean the inner side... can use earbuds (to clean the two holes), berus gigi (to drag the dirt out) also... cannot upload foto somemore... already max size... haish!
