75 280z problems when accelerating

[The moist shaft]

Whenever the car accelerates it will bog down and then pick up a few secounds after. I can hold the gas in a steady position and it will bog down then pick up. Also whenever i get to around 4g rpms it will struggle to continue further. Any help will be appreciated.

How do your plugs look? Car been sitting awhile? Changed your fuel filter? How is your fuel pressure?

EFI tune up, Check for vacuum leaks and poor elecrical conections first, As well as the above stated.
