Re: Idle speed

["David Teitelbaum <jtrealty@xxxx>" <jtrealty@xxxx>]

Assuming all of the systems are set up correctly and the idle motor 
has full control (the 3 brass screws are closed and no vacuum leaks 
idle ECU is working, idle micro is closed) there is a thermistor on 
the water distribution pipe under the intake manifold. As it warms up 
it tells the idle ECU to lower the idle speed. Another thing to check 
is the control pressure regulater aka warm-up regulater. It is on the 
left valve cover. Make sure the vent hose isn't kinked, it's the short 
"U" shaped hose. Make sure the wiring plug is on securely. I would 
check it out first as it has more to do with the idle quality 
immediatly after you start the engine. Could also be a fuel delivery 
problem like a dirty fuel filter, kinked pick-up hose in the fuel 
tank, worn out fuel pump etc. When the engine first starts cold it is 
not running on "regulated" or control pressure so the pressure from 
the fuel pump is important.
