car stalls when i give it gas

Hi, my car has just under 90, miles. Many times when I press the gas, the car hesitates for seconds and then it goes. When I press the pedal, the RPM gauge jumps to 3, skipping 1 and 2.

Eventually, it goes down to 1 and I am able to drive. This can happen anytime I need to stop the car while driving lights, stop signs, etc. The mechanic has: replaced the belts, changed the spark plugs, and cleaned the fuel injector. Any help would be much appreciated. Thanks, Dbauer. Is this an automatic or manual? So you say that it hesitates - does the engine actually rev up to rpm briefly before you get any power to the wheels?

I get enough power to the wheels to move forward a few inches before stopping, then it will do it again. It also feels that way. Your description is very confusing - it goes forward slightly and then stops? All with your foot on the gas? Try to be more descriptive. No, the transmission fluid has not been checked for level and condition.

car stalls when i give it gas

Is that something I could do, or is it something for a mechanic to do? I think you may be right about my mechanic. The check engine light does come one periodically.

I was told that it was because the fuel is too rich and the car uses to much gas. This is why he changed the spark plugs. Let me try to give a better description. I hit the gas, and the RPM shoots up to 3 and the needle goes down from there. As this is happening, the car moves forward a little with with little to no power. Once the RPM gets to the car is able to accelerate.

First, see if you can find out what the exact error code is that is associated with the check engine light. Second, it may be that you are misunderstanding you mechanic. But if not then you surely need a new one. There is absolutely no way whatsoever that changing spark plugs is going to address a problem of running too rich.For the car, stalling is exactly the dead engine.

No one wants to experience this frustrating feel. The car engine had died due to a wide range of problem-related to the airflow, mechanics, or fuel.

Here are a couple of reasons when mentioning to this issue, in particular,…. Your vehicle will have more abilities to stall if it has a manual transmission. The cause of this issue is a stick shift related to the clutch. Having said that, the automatic transmission utilizes a torque converter.

The purpose is to manage the fluid of the transmission as well as it keeps the operation of the engine when stopping.

Is the torque converter faulty? So, it is sure that your engine likely stalls out. Frequently, there are many reasons for failing the torque converters such as overheating, issues related to stall speed, or dirty fluid.

Car stalls at red light or stop sign, do this and make you car run like new

If you want to check the torque converter, it is necessary to test a stall speed. Initially, it needs to determine the RPM of your vehicle.

Hence, it is necessary to locate the tachometer yours, by a tool to measure RMP. Behind the wheels of your car, you ought to place the immobilizers so as to prevent their movement. Then, it cranks the parking brake.

It begins pressing the foot brake and starting the engine. From the park to the drive, it needs to change the gears. Keep in mind, you do not brake with your foot, instead, you will hit the gas pedal. It continues to press the brake pedal with the other foot in order to engage the pedal of the accelerator for 5 seconds.

It checks the tachometer. It must read low in comparison with what it ought to be. The first, it removes your foot from the pedal of the accelerator and the next is the brake pedal. Finally, it cranks the parking brake back.

Everything from electrical to fuel delivery to vacuum system issues can all cause a rough-running, stalling vehicle. Misfiring is one of the first symptoms you will see as a symptom of incomplete combustion due to improperly firing ignition components.

As the situation progresses you will have trouble starting the vehicle and your fuel economy will drop dramatically.

Finally, as the ignition system reaches the end of its life, your car will misfire and start to stall. Expect the engine to sputter, cough, and jerk, especially at higher speeds. Irregular sparking will cause the car to stall and it may shut off completely when you bring the car to a stop. One of the first signs of a failing fuel pump is hesitation under acceleration.

As the problem progresses, the car will lose power when idling, and eventually it may shut down completely. A failing fuel filter may exhibit similar symptoms to a failing fuel pump. Power loss, especially on acceleration, may be the first sign. As flow continues to be impeded, the fuel filter may ultimately lead to a no-start condition, as fuel can no longer get to the engine.

The tiniest of leaks can cause engine performance problems. Expect a rough or too-fast idle speed. Misfiring or hesitation during acceleration is another common issue with vacuum leaks. As the leak gets worse, the car will begin to stall.

Bad electrical connections : Modern cars have an extensive electrical system, and a bad connection or bad ground can cause a number of issues. Dim or flickering lights can be a sign, as well as difficulty starting the car. The car will make a clicking noise, much like a dead battery or loose battery cable.

Dirty or defective idle control valve : The idle control valve controls the amount of air that goes into the engine, which allows the computer to maintain the proper engine speed. When an idle control valve becomes contaminated or stuck, it may lead to an unsteady and rough idle. The car will stall if the valve is too clogged or when it finally fails. If, while holding the accelerator pedal down, a small amount of pressure keeps the car running at a stop, the idle control valve may require attention.

In most late model cars, this problem will usually trigger the Check Engine light. A top-rated mobile mechanic will come to your home or office to determine the source and cause of the stalling condition, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.

Car engines quit because of a variety if issues around air flow, fuel or mechanics.

Some common reasons for motor vehicle stalls include:. If your torque converter fails, the engine can stall out. Torque converters can fail for many reasons, including dirty fluid, overheating and problems with stall speed, which is the RPM at which your torque converter shifts power from the engine to the automatic transmission.

In order to check your torque converter, you might have to perform a stall-speed test. Place immobilizers behind your wheels to prevent your car from moving.

Crank that parking brake. Then crank that Soulja Boy. Press the foot brake all the way to the floor and start your engine. Vroom, vroom. Change gears from park to drive, but instead of hitting the gas pedal, do not take your foot off the brake. We repeat: do not take your foot off the brake!

Keep pressing the brake pedal, but use your other foot to engage the accelerator pedal for a maximum of five seconds. Check your tachometer for the stall speed and see if it reads lower than it should be. When you're done, be sure to remove your foot from the accelerator pedal first, then the brake pedal.

Then you're safe to crank the parking brake back down. If you need to get a new torque converter, visit an auto shop. Or, if this whole process sounds like something you totally want to avoid, just head to a mechanic and ask them about performing a stall-speed test for you.

They can make a recommendation on whether or now you need a new torque converter.

If your engine stalls out, use this information so you know what's happening, and how to handle it. We all know that secondhand smoke and smoke from forest fires can wreak havoc on the human body. The effects on a car are also similarly disastrous, though in the case of a vehicle, it requires a large volume of smoke and debris to see negative effects. People have questioned the effects of smoke on cars and how it could create stalling in the past, but it seems that a surge in debris-filled smoke has caused the car issues to increase.

There could be a few different reasons why a vehicle may stall out during a natural disaster, but all of them are indeed smoke-related, mostly in regards to oxygen intake. It might not stall immediately, but as the oxygen flowing in decreases, the vehicle may slow down and eventually stop.

This process starves your car of fuel, which is what makes it move forward. Sale Ends:.You know how frustrating it can be when your car hesitates when you step on the gas. Instead of get-up-and-go, you get hurry up and wait. But you can troubleshoot this common problem, maybe even fix it yourself.

It's Monday morning, and you're on your way to work in your trusty car and truck.

So when the stoplight turns from red to green, you punch the gas pedal, hoping to sail through the intersection a little, um, faster than usual. But instead of moving when you hit the gas pedal, your car hesitates. Juuust long enough for every car behind you to honk, flip you the bird, or angrily swerve around you. They're sailing right on through. So why are you sitting there, bogged down, pumping the gas until your little engine that could finally muster enough power to come up to speed?

The feeling is unmistakable. Your engine either seems to bog down when you hit the gas pedal, or it takes a second or two to respond. It's not quite a stutter, not quite a stalland it doesn't matter if the engine is hot, cold, or low on gas. There are a number of possible causes, but you're going to have to take a good look at your engine to try and diagnose the problem.

You can do this by shutting off the engine, putting on some old clothes and gloves, and making sure nothing is dangling from your body that could get caught in a part of a cooling fan that suddenly decides to start running, even thought the engine is off.

An engine that hesitates when accelerating is either sucking too much air, not getting enough fuel, or misfiring.

Thanks all for your help! Air filter is newer, and the same thing happens even if i take the air filteer out. Plugs about 3 years, but this car sees less than miles a year since the plug change. I had the same issue twice on an old Celebrity. Once it was the idle air control, the second time it was a bad wire leading to it. First check to make sure there are no big holes in the air tube between the mass airflow sensor and the throttle. The holes are usually on the bottom side of the tube where you cannot easily see them.

Try disconnecting the mass airflow sensor and driving it. You may need to clear the check engine light afterward, but that should not be hard on an ' I have fixed the car!!! I have re -attached the MAS and the car runs like a champ!! Thank you all for the great advice! Although maybe not.

I tried it a couple more times and it did the same thing. But then I tried starting it and then when I step on the gas, it dies. I then turned off the engine and just turned the key on and could hear some kind of electrical almost a static-like sound coming from somewhere very near the alternator. Thank God for your mention of the mass airflow sensor. I have a 92 Infinity M30 that just sits in the driveway. I quit driving it, but start it up every month or so.

Last time I drove it on the road was a year ago, and it stalled at rpm every time. I figured a fuel problem. Plugged it in and it runs great! A whole year of it just sitting in the driveway - makes me sick to think about. It can also lead to Remapped car chipped. Most beginners tune up the parameters so high that the MAF stalls the engine.

What Causes a Car to Stall?

Have you pulled the plugs to take a look at their condition?Car doesn't start unless I step on accelarator,shuts off when I take it off! Will that be carburetor or Gas pump. The fuel injection system does nothing until the engine is turning starting or runningso pressing the pedal before you start will make no difference.

The fuel injectors work at any RPM, so a choke is not necessary. The computer simply feeds a little extra gas through the fuel injectors to start the engine.

On the old carburetor engines, you pressed the gas pedal before starting to set the choke position and give a squirt of fuel into the engine via the accelerator pump. This was necessary because the carburetor does not feed fuel as efficiently as a fuel injection system does at low starting RPM.

It may be likely that you have a faulty 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. 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.

I would recommend having an expert from YourMechanic come to your location to diagnose and repair your idle air control valve. Q: Car will not stay running when I take my foot off the gas pedal.
