If it didn't do that before the work you did then more than likely what you did has something to do with it . The MAF sensor can get ruined by carb cleaner and they make a cleaner just for thwm ,, some throttle plates have a coating that can also get ruined, scan for codes even if the light ain't on , you would think it's the air idle control bit it may be getting mixed signals
