Hi everyone, I am a new member and was wondering can some help me out with my problem. I have a 1983 280ZX coupe with 239,000 miles. I have a moderate stage II cam and great compression on all cylinders. The problem I am having is that while driving the car during acceleration or normal level driving the car wants to stall and hesitate. I can push in the clutch, rev the engine and then it corrects it self until it happens again moments later. The car runs, cranks great, and idles just fine. I have changed out the fuel regulator, fuel filter, new fuel pump, new fuel dampner, had the air-flow meter re-built, new distributor cap, rotor button, wires, and spark plugs, yet none of those things I have done has helped. I am thinking that I might have to drop the gas tank due to possible rust that might be restricting the fuel pick-up on the fuel sending unit. Can anyone give me any help with this ???
