After the engine warms up it starts this problem. I have taken it to two dealers, two independents, and a transmission shop. No one can identify the problem or even give an educated guess. Any ideas??? It sounds like a failing oxygen sensor to me, but nothing shows up on computer diagnostics.

Check the inside of the connectors for a green or white corrosion. If you find this, clean out thoroughly and reconnect. Ford has had bad connections due to this problem for years. Also, if you have a scan tool, you can perform a "wiggle test" to check for broken wires and bad connections.
