Faster Idle When Warm
86 6.9L. Title says it all -
I'm not sure what the deal is - after about 10 minutes of driving, the truck idles almost as high as it does when cold-starting with a fast idle; my non-fast-idle is relatively low. Fuel system does not seem to have any air leaks, I have buttoned that up thoroughly (I believe, with new lines, return stuff/caps, and a facet pump).
Truck uses oil rather quickly, perhaps this is it (more "fuel" in the chambers when warm?) I have a basically-new CDR on there, perhaps only 300 miles on it.
Thanks for your insights!
