My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Hi there. The first step is to check for any problem codes stored by engine management. This can save a lot of time money when diagnosing drive-ability problems. Most auto parts stores will do this for free. Several problems could cause the stalling you are experiencing – a dirty idle air control valve, dirty throttle body, air leak in the intake (loose or split hose, EGR valve not closing), or leaking or dirty fuel injectors, or other fuel supply issues (clogged filter, weak fuel pump, malfunctioning fuel pressure regulator). If you would like to get a more precise diagnosis, have a certified professional, like one from YourMechanic, inspect your car’s stalling problem in person so that this can be corrected properly.

Common reasons for this to happen:

Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine.

The most common reasons a Nissan Sentra engine stalling are the fuel system, the air intake system, or the ignition system. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
Nissan is recalling model year 2010 and 2011 Sentras due to the installation of an incorrect engine bolt. The bolt could cause a series of issues leading to an engine stall. The Problem: During manufacturing, a terminal stud bolt could have received zinc coating that was thicker than the proper specification.
Stalling when the vehicle is put in gear simply occurs if the engine cannot accommodate the load. Among the potential causes of that are faults in engine controls. A mechanic can test the throttle position sensor and idle control valve as well as the manifold absolute pressure (MAP) sensor.
The power steering pump uses engine power provided by the drive belts to assist with steering. If the pump is causing extra strain the system, your engine will inevitably take on the extra load. This is why when you are turning, the engine feels like its losing power.
A lack of fuel pressure or fuel volume can easily lead to engine stalling. Common culprits include a faulty fuel pump or fuel pump relay. A clogged fuel filter or bad fuel pressure regulator is also common on return-type fuel systems. Another often overlooked problem is the vehicle simply being out of fuel.
It could be a dead alternator, a bad coolant sensor or lack of fuel, just to name a few. Is your car stalling while accelerating? If so, then it could be a major vacuum leak, clogged fuel filter or a bad fuel pump. If your vehicle is stalling when driving, seek professional help to track down and fix the issue.
If your powertrain control computer is misreading idle speeds, this can cause a high idling malfunction. When your car`s throttle is malfunctioning, this can cause your car to stall or idle high. Often this is a result of dirt buildup in the air intake. Other times it can be a problem with a cracked intake tube.
Airflow sensor: When your airflow sensor is failing or dirty, it can send wrong signals to your engine`s computer that can result in power losses while accelerating. This type of issue usually causes your Check Engine” light to come on and your vehicle to behave sluggishly even when there is power.

An indication that a vehicle is not receiving the right mixture of air and fuel is if the vehicle jerks or surges forward at high speed.

the most relevant questions and answers related to your specific issue

Car turns off. First it would turn off in reverse and when I would stop at a red light or slow down to make a turn.
ANSWER : Hi there. For the reverse stalling condition, check the Idle Air Control Valve and see if its plugged up. If a IAC valve is plugged up, an engine will stall out when going into gear and could cause issues when slowing down. For the steering and stalling issue, check the power steering fluid and see if its low. If the fluid is full, then the pressure control valve in the power steering is not releasing causing the pump to load up making the engine stall. Try turning the vehicle with the engine running and at a stopped location.

If the engine stalls out, then its the pressure control valve, but if it does not stall out, then there could be an issue with the transmission.

If you need further assistance with your engine stalling, then seek out a professional, such as one from Your Mechanic, to help you.

Engine turned off but inside of car still on, now engine won’t turn back on.
ANSWER : Hi there. The symptoms you’re describing with your boyfriend’s 2002 Grand Cherokee appear to be related to a broken or worn out ignition switch or relay. The ignition switch on the inside of the steering column is attached to multiple electronic connections that send signals to a relay box; which in turn, sends the signal to the individual components. The issue could be related to the ignition switch, the relay, or any of the components in between. If you want to have the fault pinpointed in person, I would have this starting issue inspected by a trained professional to ensure that the correct repair is made.

What would cause my 2008 Dodge Carvan to shut off when coming to a stop?
ANSWER : Hello. It sounds like you have an issue with the vehicles idle control system. When coming to a stop or when parking the vehicles computer must adjust the idle in order to keep the engine from stalling from the lack of air. Most of the time this is as easy as cleaning out the throttle body. In some other cases it may be caused by a faulty idle control system or even an issue with the vehicles variable valve timing system. I usually clean the throttle first to see if it takes care of it.

My car stops when engine gets warm and while I am driving I stop on red light and car suddenly turn off and I have to hit starter
ANSWER : Hello, from what you’ve described it sounds like you are having several different issues. The starter should have nothing to do with it stalling, but it will have something to do with the car restarting if it doesn’t turn the engine well. The stalling can be from the distributor or possibly a computer sensor.

The scenario where you hit a car from behind may be from another problem, alongside with the idling of the engine. Without knowing the model and engine size of your car I can only say so much. I would suggest having a mechanic do a thorough check of the entire car to check the engine, brakes, and computer systems to see if the problems can be identified and repaired, or at the very least quoted.

Cruise control turns on at idle, but when the car reaches 10 mph the cruise turns off and won’t turn back until idle again.
ANSWER : Hi there. Check all of the grounds to the vehicle and see if there is any wires that are damaged from the taillight short. A loose ground will cause multiple problems with the electrical system and some or multiple components will not work. If you need further assistance with your electrical issues, then seek out a professional, such as one from Your Mechanic, to help you.

When the car is stopped and in gear, the engine often shakes and nearly stalls when the air conditioner is turned on
ANSWER : Hey there. There is an A/C idle-up VSV (vacuum switching valve) on your vehicle. The purpose of that valve is to increase engine speed at idle to accommodate the added load of the A/C compressor when the A/C switches on.

If the idle-up valve is not functioning, it is possible that this is a cause, or part cause, of the issue you are facing. In addition, of course, you could have engine tuning issues which are contributing to the rough operation and that should be evaluated as well during a tune up.

If the plugs haven’t been replaced for 100,000 miles (and perhaps less depending on age) they will have to come out and YourMechanic has the expertise to get them out safely without damage.
To have this scoped out further, I recommend having a certified professional, like one from YourMechanic, diagnose the shaking symptom so that it can be properly resolved.

Vehicle’s engine stops turning over when at speed.
ANSWER : Hi There,
It sounds like you may have one of two possible issues. The issue of idling and stalling may be related to a dirty or faulty idle air control valve. The idle air control valve monitors the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle. This valve is controlled by the vehicle’s computer and will adjust idle speed based upon other measurements such as engine temperature, intake air temperature and electrical system load or voltage. This is also an important function when starting the motor as it allows the motor to run and idle on it’s own once the motor fires. When you accelerate, the engine RPM increases, and as you let off the gas, the RPM slowly returns to the normal idling speed with the help of the idle air control valve making the transition from a higher RPM back down to idle speed while adjusting the air/fuel ratio constantly to allow this to happen smoothly. When the engine RPM drops below the normal range of about ~800 RPM, this often times will cause the engine to stall indicating a dirty or faulty idle air control valve.

When the truck stalls at highway speed and does not immediately start right away after, this suggests you may have an ignition coil that may be starting to fail. Ignition coils are coated with a varnish-like insulation that becomes brittle over time after being stretched then contracted repeatedly The insulation develops small fractures that open when heated and close when cooled. When open, they allow shorting of coil windings and decrease or eliminate the coil’s ability to function. This type of temperature cycling happens because every time you shut the engine off, the fan stops running, the coolant stops flowing and the temperature under the hood rises. Every time you start the engine again the coolant flows, the fans turn on, and the temperature drops. When this heat dissipates and is absorbed under the hood, it is trapped causing this cycling effect. Components that contain heat sensitive materials include parts like coils, injectors, igniters, and some sensors. Any of these may be potentially subject to this same kind of heat problem which can be very difficult to trace. I would recommend having an expert from YourMechanic come to your location to take a look at your vehicle.

Car won’t turn over. No lights come on when I turn it. Can’t even lock my doorsvor push the seat up or back.
ANSWER : Your probably correct, it sounds as though your battery is done. But it also sounds like you have charging system issues. I’m not sure that fixing your battery and charging system will solve the problem with the car shutting off, but it’s possible that it will and it’s a darned good place to start. By contacting Your Mechanic, you can have a technician come to your home or office to check out your car and help you figure out what to do next.
