Try cleaning out your Throttle Body.mine was doing the same thing.i removed the T/B and cleaned it with T/B cleaner and a soft brush.then i put a drop of PB-Blaster on the flap.Also try running a can of SEAFOME in the vacuum coming from the break booster to the intake.just make sure you put a whole bottle (SLOWLY) in the vacuum line with the car running (Made need a friend to hold the accelerator down a bit so the car doesn't shut off).or just put half in the vacuum and the other half in the crank case.after you change your oil/filter it will run a whole lot better.the car will smoke and be hard to get going after you put the sea fome in,but this is normal.just take it for a drive (At night) for about 10-25 mins. let me know your results:) Help!!! My dad passed a few months ago and we never got to Finnish building the old 280zxT..Everyday i get a little bit closer.Shes running dad..
