I would recommend the following:

1. Disconnect the battery for 5-10 mins to let the computer reset.
2. Re-connect the battery.
3. Turn the ignition switch to "on" but do not start the car
4. Connect code reader
5. Read out any codes (there should be none)
6. Disconnect code reader
7. Start car and see how it runs. It "should" run fairly normal but the computer reset will have cleared any learning that the computer did previously.
9. Drive the car for 20-40 miles in varying conditions so the computer can re-learn (optimize) the engine performance. Don't baby it and don't over race it. Drive "sporty". Stop and re-start the car a few times during this process. This can be done over several days.
10. Re-check for codes with the ignition on but the engine not running
11. Post any codes here and someone will suggest what to do next...
