I changed all four 02 sensors, the fuel pump, the TPS and put all new ignition coils, spark, plug, wires and spark plugs. Before all that I had no problem with the idle, after changing all of that it idles at 2,000 RPMs It used to idle at 800 RPMs it runs great but will not idle down.

It sounds like you have a vacuum leak or the TPS is not installed correctly. Here are two guides to help us with the TPS installation instructions as well.

Use this guide when the engine is cold only:

Check out the images (below). Please let us know how it goes.
