Took my truck in this morning for missing at idle and white smoke at idle. I thought it was another injector but they replaced the computer and reflashed with latest update. Anyone else get this yet? Truck runs great now.

I had the same problem, white smoke and rough idle.
Took it in last week, new injector for #3 cylinder and so far it is running good. "Crosses Fingers"
There must have been something corrupt with your ECU that didn't alow them to re-flash it.
