Too much gas when accelarating

[dcruz]

Hey, guys finally I have gotten my 1978 280z inspected and registered, now i

'm driving the car to work. Well, the problem that I have is that when I first start the car up it smells like to much gas is burning, the car won't shut down but the smell is pretty strong, The car has new NGK spark plugs that are gapped at 40, new spark plug wires, coil and distrubitor cap and also a water temp sensor. I have messed with the screw thats on top of the AFM, but it stills smells like gas. Once the car is warm it doesn't do as much but when I start to drive it I noticed that the smell is there when I let my foot of the accelarator the smell becomes stronger but when im just crusing with the accelarator on it it doesn't seem to smell. I have read to check for fuel pressure, to adjust the AFM and the TBS. Well the fuel pump is new,the TBS is also new, I replaced it because my rpm were going crazy, jumping from 800 to 1500 when I would come to a stop. Also I have cleaned all the connections in the engine along with grounds and my fuse links have been replaced, My main concerned is when i'm driving and I let go of the accelarator the smell is there and I have done my homework but just don't want to start messing with things because im afraid that I would just mess something else up. I would rather post here first and if some one has had this issue before they would point me in the right direction. One more thing, I don't think that this is fumes comming in because I can only smell it when I take my foot of the accelarator. Well any inputs will be most welcome. Thanks
