Question about Nissan Sentra

1 Answer

Gas gauge Last week I had a cylinder which was misfiring repaired. Over the weekend I took a long trip, and noticed that my fuel gauge was going up and down quite dramatically - and it has never done that before. I am not sure that there could be a connection between the repair of a cylinder and the fuel gauge. However, in September I have a trip of 2000 km to make, and don't want to be stuck - at the moment I just fill up when it hits the halfway mark just to be safe. Any suggestions? Should I go back to the garage which does my repairs?

SOURCE: Nissan Maxima car repair ripoff

I'm wondering if your injectors are leaking. If they are, and the car sits for a period of time like you're saying, fuel would puddle up and the car would run extremely rich until the excess puddled fuel burned off. Did you (or do you) notice black smoke from the tailpipe during the time the car is running really rough? Take a look and see - rev the engine if you need to, and see if you see some. It'd take a few minutes to burn off, and once it did, as long as the rest of the car is working right, you'd run normally. If you shut the car off for a short time (ie, getting gas, renting a movie) the car likely wouldn't sit long enough for enough fuel to puddle up for the condition to recur. If you park it overnight, that's plenty of time for the injectors to leak enough fuel for the car to run rough on startup.

No guarantee of course, but that's what sounds like a worthwhile investigation to me.

SOURCE: New Mastercylinder/brakes still lose pressure

ITS THE MASTER CYLINDER AGAIN.More than likely they are using a re manufactured master cylinders. Get a new one from MOPAR-(CHRYSLER) that will take care of your problem. Trust me I have had the same problem with a similar vehicle in the past in my shop. Good Luck, thank for using FIX YA

SOURCE: Fuel gauge registers empty after fill up

It sounds to me like you have a short in your wiring harness at you fuel tank. there is a plug on top of your fuel tank that controls you fuel pump and your sending unit that tells you how much fuel is in the tank. This plug can be a real p.i.a to get to on some vehicles, you may have to take the vehicle to a shop to fix it, if you are not mechanically inclined.

It seems to me you may have a very lean air/fuel mixture so when you open the throttle for more air there is no corresponding fuel coming to give you enough power.
My first port of call would be the fuel filter. It may be clogged as you rightly point out. If there is no engine check light on that will iliminate the sensors. I'm sure you would have noticed fuel leaks though what would seem like very high fuel consumption so what remain is the pump.

Some garages may have a fuel pressure gauge to check the pressure but it's a lot cheaper just to replace the fuel pump. The old pump may sometimes have intermittent failure which a pressure gauge may not pick up.

Did you notice if there was oil on the spark plug wires after you pulled the wires? If so you may need to replace the valve cover gaskets. They keep oil from going on the spark plug wires which in turn can cause the mis fire.

well the first thing you should do is check the compression in cyl number four the compression should be within 5-8 of the nearest cyl if you see a significant diffrence in pressure you have a week cylinder...also is there any discoloration on the number 4 spark plug a coolant soaked or fuel soaked spark plug can lead u in the right direction..lastly i would take a look at the exact fuel pressure you will need a gauge and take a look low or high fuel pressure can cause a misfire....keep in mind that a clogged catylitic convertor can also cause a misfire do to accesive back pressure give your convertor a tap and see if its rattling ....hopefully this can lead u in the right direction ...good luck

P0300 Random Misfire

Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.

A Random Misfire code usually indicates a vacuum leak or bad gas.

NOTE: If a misfire in a specific cylinder should lead you to check the spark plug, fuel injector and compression.

Similar Problem: Van bogs down when you step on the gas


2 simple causes for your symptoms would be water in the fuel tank (pour drygas into the tank to alleviate this problem) or a leak in the exhaust system. If both items don't apply, check for any vacuum leaks under the hood. You've isolated the problem to either vacuum leaks or a fuel problem. Hopefully, this will give you a general area to look and solve your problem. Best of luck.

Check engine Light


P-0300 indicates a "multiple cylinder misfire".
P-0301, 0302, and 0303 indicates misfires on cylinders 1, 2, and 3.

The culprit could be bad gasoline, water in the gas, or dirty injectors. If you had P-0301-02-03-04-05-06, I would recommend plugs. But, in your case, I do believe that your issue IS fuel related.
I would not suspect ignition coils, as you do not have a P-0304 with the other 3 codes recorded. I hope this helps. Please feel free to get back to me if the problem reappears, for additional info.
