07 Ram 4.7 cold idle too fast

From : roger rabbid

Q: i just traded in my 2000 dakota sport for a 2007 ram 1500 slt. very very happy with the truck. before i decided it was time to unload the dakota the engine was making a noise during cold starts. i never investigated it any further except i switched back to synthetic oil from the straight weight oil... noise seemed to be less but never went away totally.. so assuming it was something getting ready to fail i traded it last weekend for an 07 1500 slt short bed with the 4.7 i loved the dakota the second i saw the first gen ii dakotas and knew i had to have one. for the few glitches i had with it it wouldnt prevent me from buying another one. i just love them. 4.7 perfomance is more than enough for the truck even with a 21 foot glass bow rider in tow. stopping could be tricky with the rear drums but all in all the freakn truck had heart. anyhow my question is technical here. when i start the ram it immediately fires up runs up to 2000 rpms for a second and idles back down to about 1100 and then drops off about a 100 rpms for the next few seconds. is there any way to defeat this so the engine fires up at a lesser rpm it seems harsh on a cold engine especially in these parts where it routinely drops below 0 in the winter. also during 4-5 upshift the transmission seems like it goes into the twilight zone and seems like the engine is going to keep reving up. i dont know if this is normal... however because it still has under 5k on the odometer i tend to be very light on the throttle and thought maybe this is the reason it was doing this. under heavier throttle it doesnt seem to do it. ----== posted via feeds.com - unlimited-unrestricted-secure usenet ==---- http//www.feeds.com the #1 group service in the world! 120000+ groups ----= east and west-coast server farms - total privacy via encryption =---- .
