Question: Avalon stutters when accelerating

1999 Avalon, 107K miles, when first driving i can press the accelerator as hard as I want and it will respond well. After warmed up 2-3 minutes, it will hessitate and shutter when I press the pedal too much. I have to gradually press the pedal to get the car up to speed - happens at any speed. Will not happen when car is in neutral. I replaced the MAF sensor, checked the EGR valve and cleaned it, replaced PCV valve and did a throttle body cleaning w/ SeaFoam. where to next? Thanks
