High Idle Concern

[JMKiser]

I have an issue with extreme high initial idle at start up. I took my 1998 Ranger with a 3.0L to the local dealer to have some work done about a month ago. Long story short, my number six plug wire got burned against the exhaust rail. Anyway, I guess they re-flashed the computer to the newest *.bin, or flash version. After that when I start the truck the tachometer jumps up to 2200 – 2300 RPM and then it settles’ down to about 1500 after a moment or two, then it finally adjusts itself to about 1100 for a few more seconds and eventually ends up at 900 – 1000 RPM. I confronted Ford about this and they said that Ranger’s and F-150’s do have a tendency to do that at start up. Ordinarily I wouldn’t be too concerned, however I believe that the 2200 – 2300 RPM high idle at start up at 0°F in Alaska is a bit much. If anyone out there joins my concern, please point me in the right direction. Regards, John from Alaska….
