Solution:Replace the throttle position sensor, this controls the idle.

This should work for any car.

With the car off, have a friend push the gas while you look at the engine, on the top you will see something moving. This is the throttle. Rock this with your hand. As you let it fall back into its normal position, notice what it is resting on, this will be the idle screw, screw it in to up the idle, out to take it down.

hope it helps
