If this has already been asked, please point in the right direction. I have a 2015 GMC Sierra, 96K miles. This is really hard to explain. When getting into the throttle on take off, the truck will bounce and jump 3 or 4 times before taking off. It is almost like running out of gas. This issue has almost got me ran over cutting across traffic. If you get into the throttle easy this issue does not occur. Only on mid/hard acceleration. The tack will also bounce when this occurs. Sometimes the tack will quit all together, not every time. When the tack quits then i cant replicate the issue. I have to turn truck off and back on to get tack to function again. When this occurs it throws no codes or lights. If you have it hooked to a computer while driving it will give a crank sensor fault. I recently replaced the transmission and crank sensor. This issue happen repeatedly before trans. change. I have also recently replaced the high pressure fuel pump. If any one could point me in the right direction i would appreciate it.
