Hey all - My 2004 4.4 75,000 mile X is in for this EXACT thing right now. Rough start-up when cold, SES light etc. They could not read a specific error code nor replicate the condition (so they say). When I went to pick the car up it started doing it a few hours later..I took it rightback but have not heard from the dealer...this was Saturday. Curious about the CPO coverage....I'm good til 100,000 or 10/10......we shall see. This is a good post - keep everyone informed about this issue...thanks John
