I'm having the exact same symptoms as smk1028 describes (post #25). It's going into the dealer tomorrow so I'll update the results this week.

It started happening 5 days ago and has gotten progressively worse, so rough that it nearly dies. It runs great after a few mins driving. "Service engine light" flashes.


UPDATE:

They swapped out all injectors and spark plugs. I don't understand why, but I swear there's more power and it also runs smooth on cold starts now.
