Hi, There can be many things that could be happening. Your spark plugs could be loose or bad, your distributor and rotor could be bad, your fuel filter could be clogged, your air filter could be clogged, these are just some starting p[oints. Good luck. Steve H.
Try replacing the distributor
try replacing the coil.
could be a clogged injector, a bad coil or a bad hall-effect switch in the distributor
It could be several things, but first I'd change the fuel filter, possibly drain the tank if there is alot contaminants in it. On_mitch
Solved this problem with new spark plugs/wires and a new distributor cap, about 100 bucks for parts If a lot of water gets sucked up into the filter box, the paper filter will get wet- effectively choking the engine out of air. Check it out in the rain some Night, In the night you can see if there is blue spark over your engine. It could be cracked ignition wires coming from the spark plugs to the ignition coil/distributor Check the distributor cap and make sure all the spark plug holes are clean. If they are clean and it still does it try replacing the cap anyway. Nissan updated distributor cap and distributor. Try replacing cap first (much cheaper).
Could be as simple as a very dirty fuel filter. I would start with replacing the fuel filter.
It could be as simple as a plugged up fuel filter. Try replacing the fuel filter.
Could use more info but, try replacing the fuel filter.
what are you trying to improve???
Spark plugs need replacing - ignition wires need replacing - car needs tuneup - dirty fuel injectors - fuel filter needs replacing - fuel pump is failing.In a vehicle that old (and with unknown maintenance history) it could be any or a combination of several of the above factors,- - - - -There are no ignition points - the rest is correct.- - - - -Added: Sorry - brain slip - what I meant to say was distributor ignition ROTOR.
It could be tune up related, fuel filter, air filter, spark plugs, ignition wires, distributor cap and rotor. It could also be a bad fuel injector(s).
