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
It could be as simple as a plugged up fuel filter. Try replacing the fuel filter.
Could be as simple as a very dirty fuel filter. I would start with replacing the fuel filter.
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).
what are you trying to improve???
Could use more info but, try replacing the fuel filter.
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).
if it has spark plugs check the distributor cap and/or rotor button for corrosion
Check fuel pump,filter,relay switch,fuses,etc. or spark plugs,wires and distributor cap.
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.
The problem could be a number of things, including clogged fuel injectors, a fuel filter or air filter that needs replacing, or a computer problem.
It could be the Tw sensor , or ur fuel enjactor dirty
The easiest auto repair and maintenance tasks you can do at home include replacing your air filter, changing windshield wiper blades, replacing broken or burned out headlights, changing the oil, replacing the battery. You could also work on flushing the your cooling system, recharging the air conditioning system, changing the fuel filter and replacing the brake pads.
It could be your fuel filter needs replaced or possibly your fuel pump itself is on its way out. I would try replacing the fuel filter first.
could be your igniion coil. It is located inside of the distributor cap. If you havent gave your car a tune up recently, it could be your spark plugs, spark plug wires, distributor cap or the rotor inside of the distributor. And if all these things are ok, make sure the engine is getting fuel. If not, it could be a clogged fuel filter or the fuel pump could be messed up. The fuel injectors could be clogged also
Could possibly be the electric fuel pump is not producing enough pressure. Or the fuel filter is clogged from not changing it, or a bad load of gas clogged it. Perform fuel pressure test if filter is OK
Check for faulty high tension wire from distributor to the external coil first. Check that the fuel filter isn't plugged. It could also be the distributor control module or a faulty timing chain.
Fuel pump, Ignition timing, spark plug misfire, fuel filter, air filter, take it to a mechanic.
Try replacing the pollen filter, that will cure the problem.
Could be a fuel delivery problem, start with replacing the fuel filter.
Check the cataylitic converter it could be stopped up
