I have 2004 AT Honda Jazz. It is around 135000 km. I have sound problem coming from the dashboard or engine.

When I press the gas pedal at the first movement after stopping or start moving on uphill road, I hear a very strange noise like frog crocking.

This sound is not coming always, I can not replicate the sound always.

When I brought the car to the repairman, the sound did not occur.

The sound is really annoying and could not found the root cause. Any opinions about this?

Thanks,
