I have been doing some research and gather information . I GONE FIND SOMEONE TO HELP US ! THIS IS A SHAME AND THE ARE AWARE OF THE PROBLEM BUT REFUSE TO DO ANYTHING ABOUT IT ! IF YOU TAKE IT TO THE DEALER SHIP AND THE RESEST THE BCM AFTER PUTTING THOUSANDS INTO A CAR !
Did you find anything out? Im having the same EXACT issue!
me to. I give it gas and it just spudders down until you let off the gas. Funny thing though, it wont do it if it's in park and it will rev up fine with no spudder of engine, until you hit the rev limiter which is 4,000 and that's normal and is what it is supposed to do

Check fuel pressure it may be a clogged fuel filter Or fuel pump on its way out Could also be transmission pressure solenoid
I have the same exact problem replaced the IAC TPS cleaned out the throttle body cleaned out the EGR valve made sure no Airways were blocked, check the charcoal canister to make sure no damage was done to that made sure the lines weren't blocked, replaced fuel regulator replaced the map sensor check for vacuum leaks. And it still bogs down when you give it full throttle or even half throttle at a rolling start. Idles great sounds great but does nothing when you give it full acceleration. WTF? CarGurus have an answer? I mean is this site just for questions cuz there is no answers no advice no hints or nothing
