ok i just bought a 76 280z and am very happy the only real problem with the car(besides some rust)is when i accelerate the car cuts out and starts jerking around at around 2500 to 3000 revs and then after that takes off out of no where. the guy who sold it to me says its just in need of a tune up but i was wondering if anyone else had any advice as to what might cause this?

 

Welcome to ZDriver!

Could be several things, so yes, you should begin with a tune up.

Check the spark plugs & wires, cap & rotor, timing, sensor wiring, sensors (especially the AFM and TPS). Also give it some fresh gas.

 

well ive been driving it around about a week now filled the tank up already and im doing the tune up thursday i have a brand new afm the guy gave me im gonna put that on whenever i can get the hosing the ones on it are dry rotted so if i move them they'll crack but he did day he messed with the timing so idk hopefully it just needs a tune up but thanks for the advice.

 

Check all the fuel filters, I got my 280Z after it had been sitting for about 5 years in a guys driveway, and I went through about 4 before I decided to drop the tank and clean it out by hand.
