Cold Start RPM
Several times this winter, as soon as I turn the key, the engine fires and runs right up to 1000rpm without the normal 3-minute wait. Did it in Whitehorse after sitting out all night at -20, but it also did it tonight after sitting outside in +20 temps. Anyone else have this issue? I'm not overly worried at this time as I'm running good synthetic oil, it hasn't sat long enough for a true metal-to-metal start, and it hasn't seemed to hurt anything, but I'd like to hear from anyone else who has the same issues.
Thoughts?

Mine has done it once when I started it in 10 degree weather without letting the grid heaters cycle, usually it only gets to about 30 here and it wont do it. Its normal, just not sure on the temp it has to see to happen.

Mine does it too. It doesn't have to be sub-freezing temps either, it does it often in 20+/- deg weather. I never personally worried about it though, I figured the computer knows what it wants. Sometimes it waits two min. and sometimes it don't. It's automatic and no way to control it, so I'm fine with it. (I have the cruise control button feature, that's seperate.)

Pretty cool feature. My was doing it the other day when it was 38 degrees. Do you have to go to the dealer to have feature of controlling it through the cruise buttons?

This one's always been flaky with the high-idle speed, I could never predict what variable would cause it to engage. With my '02, it was really simple: Outside temp below 30F and engine coolant below 140F, high idle engages after three minutes of no driver input (brake or throttle). This one does it sometimes when it's cold, sometimes when it's warm, sometimes when the coolant is at air temp, and yesterday even when the coolant was at 160F. And I've never had it jump right to 1000rpm without a few minutes of warm-up at regular idle-speed. I was mostly worried about the possibility of an ECM problem that might lead to early computer-death, but if others have the issue too, maybe it's not worth worrying about.
I've read about the cruise-control high idle, but isn't that for automatics only?

All it takes is a jumper wire and 5 minutes to work with a 6 speed.Many posts on the subject.So many its almost boring.Do a SEARCH function and find pages of reading with posts and diagrahams of which pin to jump at te ECM for 6 speed operation.You can also buy a clutch pedal switch through Cummins.Tons of info in archives of this site on it.
