The problem is : the car starts fine and begins driving fine for a minute or so and then starts puttering and losing power until the car reached operating temperature and then the car runs fine. I have had the engine temperature sender to the computer replaced but that did not help. Any suggestions?
Thanks

EGR Valve

Foul/defective spark plugs.
