Question about 1993 Nissan Sentra 4 Door

1 Answer

1993 sentra jerking problems.

My 1.6 carb sentra has a jerking problem. I cleaned the carb and have done a full service(new spark plugs the lot) Ive noticed that when the car has a quarter tank fuel she runs like a dream. The minute i fill the tank she only can take 30litres from empty(only till 3/4 tank) then she jerks terribly till it get to +-1/4 tank then its fine again. I have a theory that the problem lies with the fuel tank? Maybe there is some kind of breather thats blocked so when the tank is full the air cant escape and pushes through the fuel system? i would just like a second oppinion or maybe a easy solution as im sure this could be quite a job? Pls help.

I wanted to just give a suggestion...do you go to the same gas station to get gas? My sentra ran horrible because I kept going to this same gas station. My gas would get low and it would start cutting off and trying to cut off. I let my fuel go to almost empty and then went to another gas station to fill up. It hasnt cut of for about 6 months now and I havent returned to that gas station.

Toyota corolla 1993 2e is jerking while running


could be lots of things
in order from most obvious to least
1.) general maintenance, like spark plugs/wires and fuel filter
2.) failing fuel pump
3.) failing sensors like MAF or TP

bottom line if you have maintained your vehicle do that first
while buying parts have the store pull codes and see what else could be wrong

any further assistance should be directed to the chat room for LIVE questions/answers

No start new plugs,cap,rotor new coil icm modual put starting fluid in still no start will turn over all day


1. Check the spark plug gaps. It should be adjusted
to the thickness of a hacksaw blade.
2. You replace almost all of the ignition parts but not
the hi-tension cables of the plugs and the coil.
Have this replaced.
3. Check all the plug for sparks. Sparks must be blue
in color to indicate good voltage to burn the fuel
and run your engines.
4. When everything in the ignition is working, check
the fuel at the carb if it has a good spray.
5. Check the air-fuel adjuster at the carburetor. From
full close position, turn 2-1/2 full turns counter
clockwise.
6. Then, start your engines and go.

CAR JERKING AROUND 30,000 MILES


check the fluid for the color and smell.if the color is dark or the smell is burnt,your tranny have internal problems,also early hyundais had a lot of problems with the transmisions,internal failure as well as the valve bodies goin bad,if the service was done and you still have the problem its likely that your transmision needs a better diagnostic,if you are under warranty then there should be no problem.

Remove the large hose that is coming from the air filter at the throttle body. There is a large butterfly inside that is open when you push on the gas pedal. Get some carb cleaner and clean this as good as you can. See if this helps or cures your problem

The cilynder #1 and spark plug is wet with gas,I did chenged the injector an fuel pressure regulator,still the same engine is shaking, nissan sentra 1993


Did you change the spark plug?? Your car (1993) has a distibutor assy, which means it has ignition wires for each plug. How are your wires??cap?? rotor?? Have you ever done ignition tune up?? If the answer is yes and you have already installed new injector and pressure regulator (althoug it still could be a injection issue/ECM or computer, because ECM is what drives the injectors. If the ECM or wiring to #1 injector has an issue, the injector will not fire off and put gas into the cylinder, resulting in a misfire.) Remove #1 injector connector and check to see if you have power/12V on one side of the connector. If you have 12V there, than check the other wire for continuity to the ECM. You will need wiring diagram to find the right wire color at the ECM. That other wire goes into the ECM to the driver which opens and closes the injector depending on your demands as far as gas pedal input. That driver may be bad, causing the injector not to shoot gasoline. Than I would be looking into a engine issue, such as burned valve, or head gasket problem (coolant getting into #1 cylinder, flooding your spark plug). Tough to diagnose over the computer and not looking at it my self. Let me know what you find.
