Is there a way to increase the engine idle RPM. My 04 idles at 475 rpm and is so quiet it feels like the engine is off???
I would like to have it idle @ 575rpm.

I suspect there is a requirement for a tuner. I would bet the dealer could set it to whatever you want if you make a good arguement, like "that is what I want unless there is a good reason not to do it".

as you know your truck uses a electric throtle.the pcm only knows to open the throtle so far, to what is the idle position
your problem is most likely that you have some carbon build up around your butterfly. just remove the rubber intake hose, push open the plate. spray with some carb cleaner. wipe till it is clean on both side and your idle should come back the correct speed
