1). Turn ignition to Run, but do not start engine.
2). Wait for all idiot lights to turn off (last one will be the the throttle indicator - the two half-moons w/ a lightning bolt between them).
3). Over the course of 15 seconds, slowly depress the throttle all the way to the floor. Try not to waver or be too jerky, just a nice slow, smooth push.
4). Over the next 15 seconds, slowly let the throttle out in the same manner.
5). Allow car to sit for about an hour. (This is in the original procedure list, but i tried waiting just a minute and it worked anyway.)
6.) Start car and drive as you normally would.

Vehicles equipped with engine and transmission computers may require a relearn procedure after the vehicle battery has been disconnected. Most vehicle computers memorize and store vehicle operational patterns. When the battery is disconnected, the information may be cleared. If the information is cleared, the computer will go into default mode in order to operate the vehicle. The vehicle computer will relearn operational patterns each time the vehicle is restarted. The relearning process may take up to 40 or more key cycles.
When a specific engine component is replaced, a relearn procedure may be required. If the relearn procedure is not performed, the vehicle may exhibit the following:
Harsh or poor shift quality
Poor fuel mileage
Hesitation or stumble
Unstable idle or stalling
Lean or rich running conditions
If an accessory component was replaced, a relearn procedure may also be required. The following systems and components may not work properly without a relearn procedure:
Anti-theft system
Steering system
Power window system
Power sunroof system
It is important to reset any Diagnostic Trouble Codes (DTC-s) before performing the relearn procedure. Most relearn procedures can be performed with the use of an OBD-2 scan tool.
NOTE
This reconnection procedure is to be performed anytime the battery has been disconnected.
Connect the battery negative cable to the battery post and tighten the clamp nut to 45 inch lbs. (5 Nm).
If the vehicle is equipped with Electronic Stability Program (ESP), once the battery is reconnected, the Steering Angle Sensor (SAS) in the clockspring needs to be calibrated.
NOTE
The SAS requires calibration anytime the battery or an ABS (ESP) component has been disconnected for any length of time. If the SAS is not calibrated following battery reconnection, the ESP/SAS indicator lamp is illuminated following 5 ignition cycles indicating the need for calibration.
To calibrate, perform the following:
Start the engine.
Center the steering wheel.
Turn the steering wheel all the way to the left until the internal stop in the steering gear is met.
Turn the wheel all the way to the right until the opposite internal stop in the steering gear is met.
Center the steering wheel.
Turn off the engine.
