Engine/Transmission (1998.5 - 2002) How low can you go ? ? ?

[d.miner]

okay, I've tried searching the forums and I'm not finding anything.



I know I've seen this discussed before... just can't find it.



Dodge says they have a tool / device that can lower the idle RPM on a 24 valve. Cummins says they can't help as we have a Dodge ECM.



My truck idles around 850 RPM and I don't like it (too high!). Thinking of getting it lowered but I believe I read somewhere of dangers to this.



Is anyone aware of this?



I'd like to get down to the 659 - 700 range.



Your thoughts?

850 RPM sounds normal

Seems to me that it would cause EGTs to fall too low, which would cause unburned fuel and polution. Right?

I'd like to know if there is a way to lower the idle as well.

Come on guys... . I can't believe someone out there doesn't know the answer to this... !
