civic97dx

I did a search and may have found a poss. solution, but figured posting a question would not hurt. I have a 97 coupe with a 00' gsr swap and a drag gen three kit. I'm running hondata s200 and rc550's. All was good unit about two weeks ago when I started having idle issues. Now when the car gets up to temp and i come to a stop light, the idle drops real low and surges. If I don't hold my foot on the gas, it will die. I'm leaning towards a iac valve but don't really know the best way to diag. the problem now that it has hondata. Any help would be great
