I have a 91 SE w/ 150K...I've replaced fuel filter, plugs, 02 sensor and have removed the AIV components.

Sometimes it will idle just fine...most of the time it will hang around 1K and will surge anywhere up to 2.5K...sometimes it will rev from 1K to 2K repeatedly almost like I was tapping the gas...

Does the KA have a PCV valve? What else effects/controls idling?

I don't know if it's related or not, but today for just 5 minutes, when I wasn't giving it gas the RPMs would just drop and the engine would die. If I gave it a little gas, it would stay alive and the engine would stutter a little, if I gave it full gas it seemed fine...
