I have an SCT if you need a scan a code. On duratecs the idle starts off high to warn up the cats, maybe you don't let it warm up and let the a/r ratio find it's place. Mine sometimes does that when I don't have enought time to let it settle at or near idle.

Are you really letting it warm up though? Maybe if you buy my SCT flasher and cams it will fix it, jk.
