Might be a problem with idle/throttle learning.
Reset the ECU by pulling the battery and waiting for a bit. The first time you start the car, start it cold and let the car idle by itself for ~10 minutes without any accessories or A/C on. See if that helps.
If that doesn't help, try a reset again and do same as above, except run the AC while it is doing the idle learning.
