my 98 civic ex d16y8 idles at a surge really fast when im sitting at a stop for about a minute or longer and the car wont move unless i turn it off and turn it back on. i had 2 cel codes one for idle air control valve i replaced that with one from a honda dealer used, the cel went off, i thought that would of stopped it, but it did stop the idle surge when coming to a stop when ever id come to a stop it would surge slowly..the other cel light is for the 02 sensor to cat, which i dont have, could that be the problem? any help would be great
