I have a 2000 Durango with the 4.7 and am having a problem with the
idle also. Basically, when idling with the AC off the RPMS bounce
between 500 and 1000. When it gets to 500 or below, it seems to
sputter like it is going to die but then catches itself and revs back
up. When sitting at a stop light and idling, I often catch myself
inching forward if I do not keep a heavy foot on the brake. With the
AC on, it still bounces, but between around 700 and 1200 and it does
not sputter like it does when it gets to sub 500. My problem does not
go away after driving for awhile however some times it seems fine but
most of the time I am afraid it is going to die on me. Any
suggestions? I would like to get an idea of what it COULD be before I
pay to have it worked on.
Unfortunately, no, the problem does not go away. I also see the
problem driving along at a steady speed. When driving it's not a
drastic increase and decrease, but never-the-less the RPM's are not
stable like they used to be. This morning it ran fine, but the
temperature was in the mid-30's...
Is there an ambient temperature sensor on the vehicle?
