I picked up a 07 5. 9 two weeks ago & I'm wondering if I should be on the look-out for anything in particular. I say this because my 04. 5 had six bad injectors from the factory & it was a bear to get them to fix it right all at once. Can I get the hight idle through the cruis control turned on in this truck? The only thing I have noticed so far that concerns me is rough idle cold & warm. The other morning when it had been in the low 20's over night when it had put itself on high idle it sounded like it was only hitting on five cylinders. I blipped the throttle & it smoothed out some. I hope this isn't a road I have been down before.
