I have an 86 Nissan pickup with a z24 motor in it, yes the weird 4 cyl. With 8 plugs. It has been lurching when I let off the throttle or sometimes when I accelerate. Its been doing it for a year and won’t do it all the time it is intermittent but does it more then it doesnt.

Hard to say. If all the routine maintenance is up to date, first thing I’d do is probably to test the EGR function. It operates on a vacuum signal, and that might be produced during the situations you describe, when the throttle position abruptly changes.

A lot of things it could be but a bad spark plug, plug wire, or worn distributor are possibilities.  
And yes, those things can be intermittent.
