Could this cause ur car to stall in warmer weather? My car never stalls during winter months. But from spring on its a neverendin

During warmer weather my car stalls continually. It starts back up but will stall again if u drive a block or 2. If u let the car cool off for about 30 min or so u will go for a couple of miles before it satrts stalling again. During winter months it never stalls a single time. Plz help

My car has 16500 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
You should have the check engine light and engine scanned to see if the engine may be running lean due to low fuel pressures or clogged injectors. You should also have the mass airflow sensor cleaned and checked for proper readings and replace if not within specifications. The vehicle runs richer in colder weather and may be the reason for not stalling. You should clean injectors, clean throttle body and idle control valve then clean mass air sensor and relearn idle.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

The main cause of engine stall at high temperature is rapid fuel boiling by increasing fuel temperature. This causes a lot of vapor. Such vapor flows into the fuel pump which leading to decrease the pump load and the current consumption of the fuel pump continuously. This ultimately results in engine stall.
It may be getting too much fuel once it`s warmed up. An engine needs more fuel when it`s cold than it does when it`s warm. Cold engines run inefficiently so they need more raw fuel to fire-up, and stay running.
Some of the most common sensors that lead to engine stalling include the mass airflow sensor (MAF), engine coolant temperature sensor (ECT) and manifold absolute pressure sesnsor (MAP). The idle air control valve (IAC) and exhaust gas recirculation valve (EGR) are also well known for causing engine stalling.
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.
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.
Causes of a rough idle. Many different problems could result in a rough idle for your car or truck, including: dirty fuel injectors, clogged air filters, bad spark plugs, and a variety of exhaust system issues.
Low temperatures slow the battery chemistry, resulting in less energy for acceleration. It takes more energy to keep the battery at an efficient operating temperature, and a little more energy still to keep the cabin (and you) warm.
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.
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.
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.
Because the MAF measures the air that flows into the engine, it can actually cause the ECM to make changes to the air and fuel mixture that will cause your engine to stall if it`s sending incorrect air readings. Your engine might be fuel-starved or flooded.
Issues with the sensor system of the motor:

If one of the sensors is defective or provides wrong values, a may result in a bad fuel mixture. This can cause the car shuts off while idling.

Overheating. When your cooling system fails, your car`s ECU will eventually force the engine to stall once it reaches a certain temperature to prevent serious damage. There are a number of reasons why your engine might be overheating, including a coolant leak, a faulty water pump or a blocked radiator.
Why does it stall in first gear? The engine isn`t generating enough energy to give the transmission enough torque to overcome the inertia in the stationary vehicle, and when the gear engages it kicks back and stops the engine.
The A/C system is directly connected to the engine via the drive belt, and therefore draws its power from there. This could be part of the reason your car is stalling.
The A/C system is directly connected to the engine via the drive belt, and therefore draws its power from there. This could be part of the reason your car is stalling.
Your a/c compressor is binding up and the pully wheel isn`t turning. When the belt is stopped it puts a huge strain on your motor making it stall. Get your ac checked out. It`s likely a bad compressor and not likely any wrong with the engine.

The vehicle runs richer in colder weather and may be the reason for not stalling. You should clean injectors, clean throttle body and idle control valve then clean mass air sensor and relearn idle.

My car idles kinda rough, and it stalls when I come to complete stop and stalls when I let it run.
ANSWER : Failures in the charging circuit (alternator, etc.) do not typically cause a rough idle. A faulty throttle position sensor and/or clogged fuel injectors can cause the engine to run roughly but those are just two among many, many potential causes of a rough running engine. What will help you is a rough idle diagnostic during which the individual cylinder firing patterns can be evaluated on a scope. Those firing patterns will allow the mechanic to see if perhaps there is "a" or a couple bad cylinders and also whether the engine is experiencing a fuel system versus ignition system problem and in which cylinders. On an engine with so many miles, 240,000 in your case, compression should be tested in each cylinder as wear in the engine could potentially cause enough imbalance, from cylinder to cylinder, to cause the engine to run roughly. You have to keep in mind that typically there will be multiple issues with an old engine, for example you could have dirty fuel injectors, a sticky EGR valve and fouled plugs due to the inevitable leakage from old valve stem oil seals, or any of a number of other combinations. The best thing to do, to see if you can get additional service life out of the engine, and you likely can, is to methodically and carefully go through the list of possibilities. YourMechanic certified technicians specialize in just that so if you set up a diagnostic, a technician will get to the bottom of this for you and give you repair options so that the engine can be restored to reasonable operating condition.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

My car will be starting perfect and when the gas tank gets lower it will start having problems .
ANSWER : Based on the information you gave, it sounds like a possible fuel starvation issue, caused by a partially blocked, in-tank fuel filter or a crack in the fuel pump housing. The remedy would be to replace the fuel pump assembly and filter. The overheating may be caused by several things, including a stuck thermostat, faulty water pump, or even a cracked head gasket. I suggest having a certified technician, like one from YourMechanic, inspect the relevant systems to pinpoint the cause of your vehicle’s hard starting issue and overheating problem.

Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

My car stalls with weather under 40′ or moist out.
ANSWER : Hi there. There could be two things that are contributing to your issues with the vehicle that are playing a big roll in this. First check the manifold absolute pressure sensor (MAP) on the engine. Check to see if the harness is free from moisture since the vehicle began stalling in a car wash. The sensor may have gotten wet and shorted out. The other thing is your transmission is probably slipping. Check the transmission oil to see if its milky or lighter than normal. If so, then the fill tube seal or the vent tube got water in them. Water in the transmission will cause the clutches to slip and burn. If you need further assistance with poor acceleration and strange electrical issues after a car wash, then seek out a professional, such as one from Your Mechanic, to help you.

Car stalls all of a sudden for no reason while driving
ANSWER : Hello there, thank you for asking about your 2003 Ford Taurus. Your fuel pump in the fuel tank is most likely going bad and will seize up when it gets hot. Have the fuel pressure tested to see if you have lost fuel pressure when it stalled, then have the fuel pump and filter replaced. Make sure to check the bottom of the fuel tank for any metal particles and have the tank cleaned out of any debris found that may damage the new pump. If you want the help of a certified mechanic, have a technician from YourMechanic replace your fuel pump or fuel filter at your home or office.

Can a dead battery cause my engine to stop working?
ANSWER : A dead or internally shorted battery can not only cause a car to stall but it will also overload the alternator as the alternator attempts to both charge the dead battery and supply the car’s electrical needs. The battery can be load tested to understand its condition but if the battery is more than 5 years old there is no need to do that test as the battery would be past its normal service life. If you need a battery, you can request battery installation during which the mechanic will also test the alternator to be sure that a faulty charging system was not the cause of your dead battery.
