basically I have this issue:

driving at 50km/hr, on gear 3.
traffic light in front about 50m, tap brake, and clutch in, change to gear 2.
about 20m from traffic light, clutch in.
RPM will start to drop from 2500 to 900, then when car is about 5km/hr about 3m before i stop, the RPM suddenly increase to 1500 for about 0.5 sec and then drop to 900 when I stop.

this happen frequently when travelling slowly.

I have clean my simota open pod and also clean the throttlebody, but seemed that problem still there.

anyone have any idea whats the issue?

Maybe tb Nvr clean properly? It might also be air leak I think

clean already... even fuel injector....

could it be the sensor spoilt?

idle air control valve got clean?

I think mine no idling valve sensor.....

ecu also resetted, but still have this issue....

Check and see if it does the same thing in neutral. sounds like a leak or like bro teow said, iacv.
