Easy Acceleration Stumbling

Ever since I picked up my car from the shop (replaced AAV and adjust A/F and Idle), it stumbles upon easy acceleration. If I give a more aggressive push on the pedal it does go like a mad dog (928 type mad dog). Is this just an adjustment issue?

BTW, doing a bunch of driving today with that fuel system cleaner before the smog appointment next Sat. Just cruising is fun.

Ideal driving tune maybe different from passing smog tune. I'd say don't tinker until it passes.

Gotcha. I just got back from doing about 60 miles of freeway and stop/go street time. Still stumbles a bit on easy take off but never died. Idled perfect at stops. Shut it down once to stop at the AAA for another 1-day pass for Sunday. Gonna do more miles on it, so I can put a fresh tank of 91 octane before next Saturdays Smog Check. Also, the day is a little warm and the car never got far over the 1st bar. I am very happy so far. Would be nice to have a little music while driving, but I guess it's better while troubleshooting possible issues.
