my rx7 runs fine but it has developed an idle problem. It seems to go up and down from about 700 rpm. It just goes up and down between 0 and 700 rpm and has even died once or twice. Any suggestions that would keep me from wasting valuable time and $ would be greatly appreciated. Thanks

when it starts doing it, remove the connector from the IAC module and give it some gas and let it come back down, does it stop the iratic idlling?
