I had a similar idling problem. The car would sometimes idle fine, and then just die for no reason. Other times, the car would be idling, sometimes a little low sometimes about right, and then it would suddenly shoot up to about 1500 rpm. Then it would slowly drop back down to the correct idling speed.

I eventually replace the idle control valve because someone on the board told me that the problem was being caused by the old one beginning to stick, so instead of openning and closing smoothly to adjust the idle, it would stick and not move. Then the computer would send a stronger signal to open or close the valve, which would then suddenly unstick. But then the valve would open or close too much.

Either way I haven't had the problem since the replaced the idle control valve.

occur with the engine warmed up. It idles ok for a few minutes after start up, then once warm, the idle kicks up to about 1200 rpm. The rpms falling off too slowly isn't a consistant problem. One other funny thing that happens, which I haven't mentioned yet, is after start up, just as the water temp starts to get out of the blue on the gauge, the engine feels like it tries to cut out. It does this a few times and then once fully warm, that problem goes away. I'd assume this is the O2 sensor kicking in just as temperature reaches a high enough level. I think I may be chasing a few problems here, but figured that if I explain everything that's happening, maybe it all ties in somehow and someone will recognize the problem(s). Thanks..
