My 03 has been idling real rough after a cold startup. Brought it in the the dealer today and he has ordered me new oxygen sensors as there is a technical service bulletin stating that they can cause this problem. As soon as they're installed, I'lll let everyone know if it solved the problem.

Mine does the same......ITERMITTANTLY.
Took it to the dealer, and, you can guess what THAT answer was..well, we couldn't get it to do it, so there must be nothing wrong... I says: DId you guys pull codes from the compooter?? They says: No, but you can leave it overnight and we MAY be able to get to it tomorrow.
My response:
On mine, it seems to happen with very high humidity.
Also, if i crank it and "get off the key early" to force a "no start/fire", then attempt a rapid "re-crank". I can make this happen. Seems like the compooter gets hung in the choke cycle or something. If I wait 60-90 seconds, what ever it was "resets" and all is well .... (!!)
