Any advice, poorly running Boxster

It wouldn't hurt to clean the throttle body, also.
Just don't forget to re-calibrate the throttle before starting.

To calibrate: Turn turn the ignition switch to the on position (not run) for one minute to allow it to calibrate. Turn the ignition back off for 10 seconds and you're ready to go.

Ok, I have started and run the car since messing with the MAF and did not do this calibration. Should I still do it or is it too late?
