So, my situation is that I bought a 2002 Nissan Altima. Almost immediately, I started to have various issues. Almost everything on that car, including a new engine AND block, as well as a new mass airflow sensor (and a new airflow manifold to go along), two new cat convertors, new spark plugs, new radiator and fan, almost everything. Now my issue is that the car idles really low, with very low RPMs, and often stalls, including while driving. This happened, so I got my catalytic convertor replaced AGAIN, on my mechanic's suggestion, and within a few hours it happened again. My check engine

The most common reasons a Nissan Altima 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.
There are three major causes for a stalled engine: A lack of fuel, a lack of air flow and improper ignition. Running out of fuel is one of the most common causes of engine stalling, but dirty fuel injectors or a plugged fuel filter can also be the culprit. Your engine needs air to run properly as well.
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.
Immediately turn on the vehicle`s hazard warning lights. They`re the universal sign of distress. If you`re unable to pull completely over onto the shoulder, or if the car is stalled in a traffic lane, do not attempt to get out of the car! Similarly, never try to cross a highway on foot.
If your car`s transmission has an internal pressure problem, it can cause the torque converter to lock up, causing your car to stall. Though not as often the culprit of engine stalling than others, the transmission shouldn`t be overlooked when searching for the root cause.
Faulty spark plugs can cause the car to exhibit starting troubles. Worn out plugs does not produce sufficient sparks, which is needed for starting the engine. This results in the engine to stall and fail to start quickly.
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.
Automatic transmission vehicles need to manage their level and pressure of transmission fluid when the car is idling. They do this with a component called a torque converter. When this converter fails, your engine will stall.
Stalling the engine in a manual car is NOT bad for the vehicle, so long as it`s not done 8 or 10 times every day.
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.
Bad solenoid may be causing vehicle to stall.
Many modern vehicles are designed with several fail-safes to help protect the engine in adverse conditions. One of this is an automatic shutoff when the oil pressure drops to a certain level, or the oil level drops too low (note that this is not true for all cars). This causes the engine to stall and die.
A clogged fuel filter causes low fuel pressure that results in a lean fuel condition and engine misfire. This can result in poor fuel mileage, rough idling and possibly cause the check engine light to come on. Once that light is on, it`s time for a trip to the repair shop.
When your vehicle splutters and eventually stalls it could be a sign that your car needs new spark plugs. The spark plugs, while small, are a critical part of your engine and are what “spark” air and fuel mixture in the engine sending power through your vehicle.
In most cases, this will occur due to an obstruction of fuel or the inability to correctly mix the right ratio of fuel to oxygen. This could be due to dirty or clogged fuel injectors, throttle body or a mass air flow senor or idle control valve that is faulty or needs to be cleaned.
Stalling most often occurs because of a problem with the air to fuel ratio inside of the vehicle`s engine. Leaky air intake tubes, a dirty air filter, or various other airflow issues can potentially disrupt the air to fuel ratio and cause the vehicle`s engine to stall.
Engine stalls are a common sign that your air/fuel mixture is off or your spark plugs need replacement. The stall can also be caused by faulty spark plug wires.
The signal from the coolant temperature sensor tells the engine`s computer when to apply extra gasoline during a cold start. A faulty sensor can confuse the computer, keeping it from providing enough fuel. As a result, the engine may hesitate or stall.
Another symptom commonly associated with a problematic crankshaft position sensor is intermittent stalling. If the crankshaft position sensor or its wiring have any issues, it can cause the crankshaft signal to be cut off while the engine is running, which can cause the engine to stall.
This sensor controls ignition timing of the engine and when it fails the computer does not know when to ignite the cylinder causing the engine to stall and not start correctly. I would recommend having a technician from YourMechanic come out and replace the sensor.
Your Vehicle is Stalling and Sputtering
Rough running can also happen as a result of a faulty fuel pressure regulator. There are some cases where you will not be able to start the engine at all.
Number 1 – Bad Battery
A bad battery is one of the most common reasons that cars stall. Most people think that if a battery is dead, the car won`t start. Truth is, if your battery is going bad,your car will run but you`re at risk of stalling out.
Stalling is caused by a loss of air, fuel, or electricity while the engine is running. By identifying the problem yourself, you may be able to repair it, or at least know what type of repairs you`ll need to pursue. As frustrating as a stalling car can be, fixing it can actually be pretty easy.
A lot of stalls are caused by releasing the clutch too quickly, or by forgetting to apply the clutch when you`re slowing to a stop. This is why stalling is most likely to occur when you`re in a queue of traffic, when you`re waiting to join a roundabout, and when you`re attempting a hill start.
