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.

This sounds like a vacuum control problem. Since part of the problem is when the engine is cold; a thermal switch is venting vacuum until the engine warms up enough to shut down the thermal switch, thus restoring a steady idle. Vacuum can be affecting high rpms while running too. You could have a misrouted EGR vacuum line opening the valve at the wrong time. There are sometimes hose routing decals on the radiator shroud or under the hood. These can be visibly checked.

clean out the fuel pressure regulator with carb cleaner spray(a good clean ), then spray dry lube into it. This part is located on the fuel rail, sits at the front of it, has three connections/holes and fuel comes out momentarily after disconnection.
