2000 F250 SD, V10, STD cab, 8' bed, 4 speed auto w/overdrive. After sitting for several hours, starts just fine, but won't idle. Drive it for a couple of minutes and it will just barely idle @ 400 RPM in gear. Drive it 10 minutes or more and it idles just fine @ 700 RPM in gear. Any ideas as to what is wrong?
