Could you rephrase the symptoms and what you have done (english). Have you inspected the idle air control motor? .......................air intake restriction + not enough fuel=low idle.

I have already changed the new idle air control, but it didn't seem to help. Can you help me with another way?

Is the problem LOW idle or low power at other RPM range? Your question and symptom description was very confusing to me.

It's the RPM that I'm wondering about. So the problem I have is when I start the engine the RPM would be normal, but when it warms up, the RPM would drop down to 0 and the same goes to stop signs or stopping at the red lights. When I drive, then RPM would be back on normal cause it has to and whenever I stop, like I said it would drop to 0. So do you have any ideas to help?

Is it stalling and you have to re-start it , or do you have to keep your foot on the gas to keep it running at a light? Have you at any time messed with the 'base' idle screw? -hopefully not. '0' RPMs would mean it's not running , so either your tach is not accurate or I'm not understanding something in your description.
