What might cause a 2001 Chevy Impala to idle up and down?
A bad idle air control sensor or a bad throttle position sensor.
What engine control or sensor would cause black sooty exhaust above idle speed on a 1988 merkur xr4ti?
Could be EGR Valve.
Where is idle position sensor?
Idle air control valve sensor is located around the carburetor .
Where is the idle sensor located on a 1987 Chevy Celebrity?
The idle speed is read by the Engine Control Module(computer) and adjusted as necessary by use of the idle air control in conjunction with the throttle position sensor. There is no separate idle sensor as such.

What would cause 5.8 liter to have high idle?
High idle can be from a malfunctioning coolant temperature sensor, idle air control, throttle linkage problem or a intake manifold leak or (vacuum leak). I have come across many v8 fords with intake manifold leaks. Unplug the connector on the idle air control, if it still has a high idle, it will either be the idle air control seized, throttle linkage or a intake manifold leak (air leaking into the manifold through a gasket or vacuum leak) If the idle comes down it will be the coolant temperature sensor or a power train control module problem. A scan should pickup a coolant temperature sensor out of range fault code if it's at fault.
