Chrysler Repair: Slight hesitation under light throttle, negative battery cable, throttle position sensor

Question
I have a 2001 Chrysler T&C minivan with the 3.8 engine. Recently, I have been experiencing a slight hesitation under light throttle, both at highway speeds, as well as when slowly accelerating from a traffic light. The problem is accentuated when the vehicle is cold, and would sometimes even stall when put into "Drive" after backing out of the garage in the morning. I use mid grade fuel and have also recently replaced the plugs & wires with mopar products. My mechanic also checked and cleaned the throttle body with no improvement. Nothing shows up on the diagnostic system, and it is not transmission related.
Do you have any suggestions?
