Ok basically, My 300zx turbo, sputers alot off the line and requires you put your foot to the floor to get it to more than inch sometimes when sittin in traffic or a light. Now if it has not run all night, in the morning when im off to work it will run like a dream! But when im on break or off work it has the sputtering problem and acts like its being flooded. This leads me to believe, that it could it be a fuel to o2 mixture issue? like an O2 sensor or some sort of sensor be bad so that it is flooding it out. It will have a rough idle if it has ran for a bit aswell. Please help me out I Love my lil Datsun!
