300zx bucks at full throttle please help!!

[rootbeer300zx]

Hello I'm new to this whole 300zx thing, but not new to the turbo car world I've been having this problem with my Z I just picked up. The car will not go full throttle it bucks and cuts. If I step on the gas very lightl, and don't hit boost its fine. Somethings. When I first start it I can hit boost but there is still lack of power. I checked the codes I get a code 53( right o2 ) but I can't see this giving me the problem. Thanks for the help!

Try adjusting your TPS:

Also do a boost leak test.

Fuel pressure as well as what everyone else was saying.

Sounds to me like fuel pump is dying or filter is clogged, something with the fuel system.
