At this point they are considered incertae sedis;in other words, we know that they are theropods; and probably coelurosaurs; but we don't know who they are related to or how they fit into the big picture of theropod phylogeny.
Idle speed is adjusted by means of the idle control valve, which is a solenoid-operated valve that is generally automatically adjusted by a computer. One problem that can occur with this component is a loss of power (from a severed line or a short) but a more common problem is simply dirt and grime.
5. Use a test light if the idle speed did not do what it was supposed to. Hook it up to the idle air control solenoid and watch the light. 1  The light will either flash or become dimmer for the four circuits if the valve is at fault..
