It is "surging" or "searching"... have you had the car tuned? My car did this after I swapped the T/B and intake, it was acting like it was re-learning all the different perimeters of air and adjusting the fuel.

sounds like a vacuum leak, mine did it after fast intake install, the map sensor fit a little loose on the rear of intake and came out while driving, check for vacuum leak.

If it was ok before I would start by looking for a vacuum leak somewhere around the intake to include all the vacuum hoses.
