My 2004 Nissan X-Trail is intermittently stalling at traffic lights and stop signs.

I drive a 2004 Nissan xtrail. My car has started to intermittently stall when I am stopping at traffic lights and stop signs, usually on a slight or steep hill. It has been doing this for some time and is progressively getting more frequent. I have had the fuel pump, throttle, crank angle sensor and battery replaced as a result, however the problem continues to occur. When I first bought the car there was a hole in the O2 sensor (or exhaust manifold) which caused a high pitched noise. A mechanic welded this hole to stop the noise so I'm wondering if this may have contributed to the proble
Experienced mechanics share their insights in answering this question :
Hi there. Having the exhaust manifold repaired should not have contributed to the engine stalling. Assuming, the Check Engine Light is not coming on, leads me to believe the ECM (engine control module)/computer is not recognizing the fault. As you already know, replacing components without proper diagnoses, can be expensive and time consuming without resolution.

The engine stalling, could be the result of a faulty IAC (idle air control) valve, a faulty MAF (mass airflow) sensor, incorrectly calculating the incoming air to the engine, and/or an air intake leak. To reduce the possibilities, I recommend having your vehicle’s stalling engine be diagnosed and repaired by a certified technician, such as one from YourMechanic.

Nissan X-Trail fuel leak (2001-2007)

Some cars built between June 2000 and November 2004 had fuel leak issues. The fuel tank filler tube is susceptible to rust around the mounting bracket. This has been known to create a small hole and cause fuel to leak during the refueling process.

Fuel pressure can be affected by a dirty fuel filter which is located in the tank. A faulty throttle potentiometer will reduce engine power as it restricts air supply to the combustion chamber. A faulty throttle unit also affects gearbox shift quality as described. Consider having it cleaned with carburetor cleaner.
The Nissan X-Trail seatbelts won`t latch

Seatbelts play a vital role in safety, because they stop you hurtling forward in a crash. And they`re designed to work in tandem with the car`s airbags. So, any X Trail seatbelt issue is a big problem.

The most common sensor which can lead to your car stalling is the manifold absolute pressure sensor (MAP) or the mass air flow sensor (MAF). Most cars typically have one or the other.
Your car may have a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle.
An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
A Malfunction Indicator Light that stays on but doesn`t blink typically means your Nissan should be serviced soon but isn`t in jeopardy of being harmed right away. You may be able to keep driving your vehicle, but you should schedule a service appointment with us when you get a chance.
This usually means an electrical system problem; dead/discharged battery, broken/loose drive belt or belt tensioner, alternator fault or blown fusible link wire to the alternator or blown fuse in the engine fuse box.
Jerking or shuddering is usually down to one of two things: Either the metal belt inside the transmission which provides the drive is worn and is slipping, or; the transmissions valve body is faulty and needs replacement. Either way, it`s a fairly major repair.
Some electrical problems that could cause a car to stall include: Corroded, stripped or detached electrical wiring. alternator. A bad battery.
Will a bad O2 sensor cause rough idle and loss of engine power? You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling. Bad oxygen sensors disrupt all kinds of essential engine functions, including engine timing, combustion intervals, and air-fuel ratio.
Bad solenoid may be causing vehicle to stall.
Nissan Vehicle Reputation

The brands are often compared to one another to determine whose vehicles are the best. Nissans have an excellent reputation, second only to automotive giants Toyota and Honda. All 3 Japanese brands are known for their reliability, longevity, dependability, and affordability.

Engine issues make up roughly 18% of all Nissan owner complaints . The majority of the issues have been reported by Altima owners.
Trouble accelerating can come from a few different engine issues. These include, but are not limited to, dirty fuel injectors, low fuel pressure, and restricted airflow. A problem with the mass airflow sensor, throttle position sensor, or engine speed sensor can also cause a car to have difficulty picking up speed.
There are a few reasons why your car might be struggling to accelerate. It could be due to a problem with the timing belt, the spark plugs, or the fuel injectors. It could also be because you have a dirty air filter or a clogged fuel filter. The fuel system may also be low on fuel.
The most typical causes of a car not accelerating while driving include a faulty sensor, contaminated fuel or air filters, or a faulty timing belt.
System malfunctions include machine malfunctions and operating system errors. System messages identify these malfunctions and errors to the operator.
Automatic Emergency Braking (AEB) System– This light resembles two cars crashing head-on with each other. This light will briefly illuminate when the car starts, and tells you when the AEB system is set to OFF on the vehicle information display.
Check the battery on the vehicle and see if it is holding a charge. If the battery have a charge, then check the battery for a load. If the battery cannot hold a load, then the battery needs replaced. Check for any loose ground wiring from the cab to the chassis frame and see if they are corroded, damaged, or loose.
There are several possible reasons for a vehicle to crank and not start. A bad fuel pump, clogged fuel filter, faulty injectors, bad ecu, failed ignition coil, or a malfunctioning sensor. It will first be necessary to figure out if there is a lack of spark, low/no fuel pressure, or a mechanical problem.
If the engine stalls while idling or driving, the engine may be running out of fuel or not receiving enough fuel pressure to keep it running. The most likely cause of this kind of stalling would be a fuel pump that is not spinning fast enough or is intermittently cutting out.

I have 97 nissan altima, It stalls when I stop at stop lights and idle, the RPM vibrates and falls down and the lights come on, it
ANSWER : Hi there. Usually when you have a problem like this, it is caused by fuel system components that are clogged with excessive carbon build-up or deposits. This creates a restriction in the efficient flow of fuel and can cause the vehicle to stall. It’s also possible that emissions system components like EGR valve, mass air flow sensors or O2 sensors are faulty. I would recommend having a professional mechanic come to your location and complete a car starts the dies inspection, so they can pinpoint the source of your issues and recommend the right repairs.

My Hyudai elantra 2014 stalled and stopped after the battery light, engine light and oil light came on
ANSWER : Hello, thank you for writing in. With check engine lights on, the first step is always scanning the vehicle for codes. These help direct your attention and ease diagnostics. The main concern is that the engine is making a loud noise. We need to determine if the noise and the battery or oil light are related. A major issue with the engine would effect the alternator charging the battery, the oil pressure, and several other components. However issues with the drive belt and other components can play a factor as well. Electrical and charging issues can cause various sensors to fail, and cause other warning lights to turn on. Only further inspection will tell, and you may need to get a second opinion. For help from our technicians, contact our service department to schedule an appointment.

Why do my interior lights dim when stopping and car intermittently shuts off at stop light. 2006 Chevrolet Trailblazer
ANSWER : Hello. This can be caused by a number of things. Most of the time if this only occurs when coming to a stop it is because the computer is not maintaining a high enough idle. This can occur because of a failing throttle body, or a problem within the engine or an intake manifold leak. This engine does have a common issue with valve seats failing causing an idling issue. I would usually start by cleaning out the throttle body to see if that corrects it. If it does not then the throttle body may need to be replaced. If the idle speed is fine then you may have a bad connection. I have seen a lot of grounding issues. Most of the time it is because of a bad ground on the engine or a bad connection at the battery ground cable. All of these need to be cleaned and tightened.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit.

(08 f150 4.6L) Truck is cutting off when making a complete stop at red light or stop sign.
ANSWER : Check the Idle Air Control (IAC) valve and see if its dirty or not functioning correctly. I recommend removing the IAC and cleaning it out. If the valve was sticking before, the computer could have caught it and adjusted the idle to accommodate the issue. After having the battery cable off, the computer is in a learning cycle which means that if the IAC is not working properly, the computer will have to relearn and may learn to shut off due to a faulty valve, even though the computer says its good. If you need further assistance with your engine stalling out at stops, then seek out a professional, such as one from Your Mechanic, to help you.

My 2010 Audi A4 stopped out of no where at a stop sign maybe a month ago. It still has not started. All lights work
ANSWER : Hello. When this occurs, the first thing I do is try turning the engine over by hand. If I cannot turn the engine over by hand, then I know that the engine is seized. If it is seized, then it will need to be replaced. If the engine will turn over by hand, then the issue is electrical. In that case, I start by testing the voltage going to the computer and the ignition switch. I always check all of the fuses first, and then follow the circuit from there. If you need to have this inspected, consider YourMechanic, as a certified technician can come to your home or office to diagnose the no start and advise you on the best next steps.
