The fuel injectors can be very dirty and in need of a powerflush with an injector flush machine. You can also do a re-learn on the computer system just in case that was the problem. Disconnect the battery cables for 20 minutes and touch the 2 cable ends together for 5 seconds. Now, re-connect the cables and start and drive car immediately for 20 minutes.
