I have a 2005 roadster limited that recently started hesitating or stalling during acceleration. I did search the forum for similar issues, Nada. I do have a code logged in the computer. It's P0453 stands for “Evaporative Emission System Pressure Sensor/Switch High. However I have had that code for sometime.

I don't have any fault codes related to ignition, fuel, or air. I have no idea of what to start looking. Typically I would wait for an engine code and then start trouble shooting from there.
