My 89 Bonneville is sluggish when she is cold when taking off from a corner or dead stop. As the engine gets warmed up it seems to get better. Within the last year I have replace the fuel pump, fuel filter, fuel pressure regulator. It got a new coil pack a couple years ago and new plugs and wires. She has 121,000 miles on her. Any Ideas what my problem could be?

The throttle position sensor may not be sending proper signals to the computer when it is cold. You may want to replace it and see what happens.
