Try using proper sentence structure please..maybe you can introduce yourself too Stranger!
What do you mean it goes from 2k to 4-6 sometimes 8?Hundred Rpm?
Is the idle fluctuating??
Cold Start Assist make the car start and go to roughly 2-3k,then it backs revs off to about 800(give or take).
If you idle is fluctuating then you need to find info on how to adjust your TPS. (search TPS adjustment 101)

With engine up to operating temperature (fully warmed) and car off. Turn the key to "on". Go to the engine bay with a multimeter and probe the green wire with a red stripe with the positive (+) meter probe. Ground the negative (-) meter probe. Set the multimeter to read "voltage"... Now there is a flat head screw near the tps itself. Turn either clockwise or counter-clockwise ever so slightly. You want the multimeter to read 1.00 volts. If it is .98 v or 1.03 v etc. It's no big deal. As long as it is pretty close.

Be sure you do this as quickly and as efficiently as possible. You pretty much do not want the car to cool down before you perform this task.
