Is the check engine indicator light lit? if so pull the code first by diagnosing it by taking a paperclip and insert it into the blue female connector just above the passenger side kickpanel just beneath the dash on the right side.

It can be anything like a bad tps or a vacuum leak but you wont really know until you diagnose them. If its a vacuum leak you can spray some carb cleaner over the intake manifold and if the cars idle dips really low in the spot that your spraying then you found your leak. But do this first take the intake or air box off and expose the throttlebody. There should be two ports/holes the upper and the lower hole. If you plug the upper hole when the car is warm and it shuts off then theres no leak but if you plug it and it doesnt die out then you got a leak. But definitely diagnose those engine codes first.

ya, accord do this shit all the time, what i do is cleaned the throttle body check for vacum leaks, then check the IAC, and if it is none of that, i give up. and just RAISE the idle, works perfectly.
