I have a 2000 dodge durango 5.9L and it idles high when in park it also will act like it wants to die out. when the rpm goes over 1 and 2 it seems fine. but than it will drop under 1 and idle funny.. we have changed the camshaft sensor that was the code it was throwing. but it didnt work. we have checked the hoses no leaks anywhere.. what do you think???

The pressure switch is only there to tell the PCM (computer) when the pump is developing high pressure. If the engine RPM is near idle (as when parking), the PCM will increase idle speed through the inlet air control (IAC) valve to prevent stalling. The pressure switch has nothing to do with the function of the power steering itself.

All the above is normal , except 2000rpm is a little high at idle . can be adjusted down to 1500rpm. the computer adjusts the engine speed . in drive the transmission loads up the engine idle drops to 1000rpm . in park engine unloaded rpm increase all normal.

I would test, or replace my IAT sensor . (Intake air temperature sensor)
If it's defective, it will send wrong signal, thus wrong mixture for cold engine.

Vacuum leaks and idle air control are the first things I would check .

Thanks for the vote, and good luck!

well the fast idle is 1 of 2 things, Either the throttle is stuck? or a super nasty vacume leak, Check all hoses carefully, if that proves good check intake leak. Something is allowing tremendous vacume into engine causing this high idle, The charging system is a whole nother story

Could be fuel pump on the way out. Could also be dying battery. Have battery load tested, and replace if its the least bit flaky.

check your idel control sensor

First check for a loose hose or a vacuum leak. If you do not find a leak most likely the throttle position sensor is stuck and causing the truck to idle high. The throttle position sensor sticks, and if this happens you will need to replace it.
