This problem is usually due to a failing ECU,

In the V6 models with OBD 1 and the 3.4L 60 degree motor.

The computer simply stops accepting signals from the sensors on the car and runs it on pre-loaded data. Another diagnoses of this same problem is related to erratic engine shake and cylinder misfire on cold starts and a check engine light that only turns off while the motor is running at long periods over 2600 RPM.
