B20b Idling drop in D mode

[mikro]

Dear all,

I have a CRV generation one using b20b engine which belong to my family, when I taking out the cr-v for a ride, I notice that the rpm meter will sometimes drop below 500 and the idling become shaky (normal RPM is 1k and the idling is smooth in this situation) when I stop in front of the traffic light and the gear is in D mode.

but after I press the oil pedal and the car move forward, the idling will become normal again.

The rpm meter will only drop below 500 when I idling for more than 1 min.

I not sure what happen, i think it might be sensor dirty or throttle body dirty, I am open to opinion :wavey:

Beside, I 'm not sure which shop who has the expertise to diagnose my problem (I'm from sunway/subang area ), so in the mean time, I need all your opinion to find a way to diagnose the problem.

Thanks you very much.

usually when it comes to idling with vtec b series its the IACV valve faulty or dirty

not sure if the CRV has it... but do check if it does...
