please email me ur reponses thanxs.

do a search.

check your throttle body i had prelude and before i sold it i fixed that issue. the tps can be tha problem. they say you shouldn't adjust it though but you can. adjusting the tps which is the throttle postion sensor should be a last resort. first you should see if the the throttle plate closes all the way which it didn't on my car and it let air seep through causing the car not to idle correctly or idle down when coming to stop.
