some they said is either throttle body dirty or vacuum leak but mine experience was evaporative canister problem.
Replaced cost is about rm100 at honda sc.

Mine is look identical to the picture.
But it has 3 legs and one of leg broken and caused the air leaked from the cracked.
Is your idling set too high?
Any leak in vacuum line?
