put a new radiator in... and a new iacv... (radiator has nothing to do with this i know) well the car started up fine.. but was still motor boating... then it started this wierd sputtering/reving... once the car got nice and warm it quit... completely... but my check engine light came on and the car idles at about 3000 rpm... (its a 93 hatch w/b18a1)

anyone have any ideas or suggestions??? car seems to run fine.. still pulls hard.

i thought maybe an o2 sensor, but would that cause it to idle high???
