Re: unstable idel problem
it could be your o2 sensor.
but some easy fixes are 1.check for vacuum leaks 2.unplug your iacv, if it fixes your idle then take off you iacv and clean it, if you put it back on and still has bad idle then the sensor is bad. clean it with carb cleaner, there will be alitle screen. youll see it. 3. take off FITV sensor and screw it all the way in that should fix your idle, if not then it didnt cost you anything. and then if that didnt work them maybe its your o2 needing replacing

Re: unstable idel problem
iacv is on the back of the intake manifold and the fitv if your car has one, is under the tb
