In the morning the engine starts fine but after a few minutes' chokes down. After it stalls it starts right back up and runs for another few minutes before choking down. On the third startup engine runs but is missing until i drive it for less than half a mile then it runs fine the rest of the day .it starts fine and runs great but the next morning the same problem occurs again. Had it diagnosed and shows all 4 oxygen sensors bad.

Yep, this happens when the PCM is going out. Here is how to swap the PCM out, you can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Please let us know if you need anything else to get the problem fixed.
