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.
If the idle air control valve checks out and the fast idle valve doesnât, then replace the fast idle valve. Itâs a little hard to get to, but replacing it is just a matter of loosening the screws, removing the coolant hoses, and replacing the valve. The Honda dealer will know right away what youâre asking for.
