ive been chasing a surging idle for about two months now... cleaned the IACV, checked the coolant for air pocket's, checked the idle screw... none of this worked... so i did ANOTHER SEARCH... low and behold i find a thread that lead's me to H/T, then i find another thread and another and so on... well all my searching has paid off... here is a link to a thread on H/T that may help you as it help'd me...
this may be a good resource for a sticky... i know it's H/T, but shit, it help's...
