Intermitent Miss/Throttle

[NZACEK]

04-350-6.0-170K-100% stock
Has had an intermitent what feels like a miss for 16 mos. 1st dealership trip replaced EGR,EGR cooler, oil cooler, couple of injectors. Dealership trips 2-6 replaced EGR 2 more times and reprogrammed/updated the computer. Tried another dealer for trip 7 and only updated the computer. The further it gets into summer the worse it gets with the heat. In the winter and spring, it would only miss during the afternoon drive home. I have read several related strings. Sounds like injectors or FICM?? Ideas??

At the same time, throttle has been unresponsive taking off from a light several times. I can keep working the pedal and it will finally take off. I have never had to kill the motor to reset it. Sounds like the electronic throttle??

I plan to put a programmer/chip on then a Liberator delete kit, but I want to get the stock corrected first.
