Change all the filters (fuel and air). check and see if all your spark plugs are firing or just change them. if it is fuel injected make sure your injectors are working. Hope something there helps get it running good.

Give it a complete tune-up, New spark plug and wire.new Ignition coil. Depending on the engine either replace ,Cap and rotors or coil packs.Also might want to get the fuel injectors service
SOURCE: high revs
being a fuel injected engine , there are many reasons this could be happening.
from the top , lets check the Manifold Absolute Pressure (M.A.P.) sensor , as it is easiest.
Find the MAP sensor , it has a couple a wires and a vacuum tube going to it and is on the firewall or fender support under the bonnet.
Disconnect the wire harness from it (small plug with wires).
If the engines RPMs drop to normal , replace the MAP sensor.

My wife had a 93 ford tempo 4 cylinder with same problem.It turned out to be the idle air solenoid mounted on the air intake manifold.

I would clean the throlle body first. Then lube the throttle linkage.
