The car runs, when you push the gas pedal it does not accelerate and there is no rpm. The engine is running smoothly, however whenever I push the gas the car does not rev. The car says that there is no engine RPM on the pedal, and reduced engine power.
reduced engine power, no acceleration when the gas is pressed (nothing happens) but the car is running.
My car has 70000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello. It sounds like you may have an issue with your throttle position sensor. This sensor sends a reference voltage to your power-train control module, which uses that to determine ignition timing and fuel trims. If the power-train control module is not detecting the proper signal from the throttle position sensor, the engine may not accelerate properly. It’s probably a good idea for you to have a professional mobile mechanic come to your location and complete a car is slow to accelerate inspection first, so they can pinpoint what is causing this issue to occur and they will recommend the right repairs be completed.

Why does my car not accelerate when I push the gas? A car not accelerating properly can be caused by a number of things. It could be due to the throttle body, gas tank, spark plugs, or the ECU. It could also be because you have a dirty air filter or a clogged fuel filter.
A loss of power is most apparent when you`re accelerating, and can be due to a number of reasons including air flow into the engine, fuel flow and even faults with the exhaust system.
Fuel injectors may become dirty over time and not be able to provide as much fuel to the cylinder as is needed. Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating.
There are many potential causes for your Chevy truck to spit and sputter. Some common reasons include a faulty catalytic converter, cracked exhaust manifold, dirty air filter, or bad spark plugs. It`s best to take your truck to a mechanic so they can diagnose the problem and make the necessary repairs.
When you press down the accelerator pedal and get minimal output, it could mean you have a problem with your fuel system. The most probable issue is a clogged fuel filter. Your fuel filter works to ensure that dirt and debris do not get into the fuel system.
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.
This can be caused by a damaged fuel pump, clogged or worn out fuel filter, EGR valve, mass air flow sensor, damaged or dirty throttle body & fuel injectors.
Bad or Dirty Spark Plugs: Spark plugs are responsible for igniting the fuel in the combustion chamber. If they are not working correctly or are dirty they don`t ignite the fuel cleanly and the car can misfire or sputter. The plugs will need to be replaced or cleaned.
One of the most common causes of a sputtering engine is an issue with the vehicle`s fuel system—the filter, pump, and injectors. These three critical components work together to ensure fuel flows smoothly from the fuel tank to your engine`s fuel injectors, and then pumps into the engine evenly.
The most common cause of engine sputtering are issues with the fuel system. These can range from bad fuel filters, fuel pump issues, or fuel injector issues.
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. Several components of the fuel or air intake system could cause this jerking or surging sensation to happen. Issues within these systems can also cause fuel economy to worsen.
A damaged carburetor may not mix fuel / air properly and can leave your car jerking, miss fire or running rough even if the spark is present. This can lead to poor gas mileage, decreased performance and general bad tuning.
If your car is not accelerating, the first thing to check is the air filter. The air provided to the engine for the combustion process passes through an air filter, which catches all the impurities and debris present in the air. With continuous usage, the air filter gets clogged and doesn`t let air pass through it.
You can attempt to bypass Limp mode by restarting the vehicle after a short wait or by removing one of the battery terminals to reset the electronic systems.
“Limp Mode” – If your car won`t accelerate over 25 or 40 mph, it could have engaged `limp mode. ` It is also known as a limp home mode, and it acts as a preservation feature. It is meant to get you home, to an auto mechanic, or safely off the road without destroying your engine.

ANSWER : Hello. It sounds like you may have an issue with your throttle position sensor. This sensor sends a reference voltage to your power-train control module, which uses that to determine ignition timing and fuel trims. If the power-train control module is not detecting the proper signal from the throttle position sensor, the engine may not accelerate properly.

Engine runs, but car doesn’t accelerate?
ANSWER : Knowing the results of the computer diagnosis as well as the part that was replaced can be helpful in assisting you with your Pontiac G3. It is possible the part that was replaced is defective and may need to be replaced. Based on what you described with your vehicle, it appears that you may be experiencing transmission issues.
The engine should never be revved up to six to seven thousand RPMs when the vehicle is not moving, as this can cause damage to the vehicle’s components. Because the information provided is a little unclear, it is hard to determine if you are having concerns with your transmission or if the problem lies with the engine itself.
If you don’t trust going back to the same mechanic that worked on your car originally, get yourself a second opinion and enlist the help of one of our certified mechanics who can diagnose why the Check Engine Light is on as well as determine why your Pontiac is not accelerating. They will also be able to assist you with the repairs needed to get your G3 up and running again.
When I press the gas pedal the engine revs but the car doesn’t accelerate. Is this a throttle or transmission issue?
ANSWER : Hi there. From what you are saying it sounds like there is a failure in the throttle body. When the motor in the throttle body fails, the throttle plate will open and close causing the noise you are hearing. I usually monitor the movement of the throttle to see if this is what is occurring. I then scan the computer for codes to see what comes up. If there are not any codes then the sensors in the throttle body should be monitored to see what is going wrong. If you want to have this lack of throttle response checked, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair your throttle body issue.
Car won’t rev or go when pushing gas pedal. Only revs up in neutral or park unless you work with it to keep it revving
ANSWER : Hello. The first task in solving this problem is to extract problem codes that are set, whether the Check Engine light is on or not. There are several problems which could cause this behavior, such as a bad throttle position sensor, fuel supply issues (low fuel pressure), or a dirty or bad mass air flow sensor. Problem codes will narrow the cause more quickly, and help avoid replacing parts that are not the problem. If you need to have a certified technician from YourMechanic can come to your car’s location to diagnose the gas pedal problem and follow through with repairs.
When I crank my car it won’t keep running unless I keep my foot on the gas. As soon as I release the gas pedal my car stops running
ANSWER : The first thing you need to check for in a case like yours is air leaks. Check all the rubber parts and hoses under the hood for good condition and connection. The amount of fuel delivered to your engine is determined by the air that flows in and any air that gets in through a leak without being measured means less fuel being injected. There are of course a number of other possible causes; a failed Mass Air Flow Sensor for example, but they will require special skills and equipment to be examined. You can have this conveniently checked out by contacting Your Mechanic. They can send a technician to your home or office to check out your car and let you know exactly what it will take to solve your problem.
I press the gas pedal but the car isn’t getting gas. The engine doesn’t rev up.
ANSWER : Good question. I want to go through a few steps with you and hopefully find your problem and save you some time and money. If you find the issue during steps, then ahead and fix that fault and you should be fine.
First, open the hood and take the engine cover off if there is one. Take off your air intake hose. This should be connected to your air filter. If it is dirty on the inside where the mass air flow sensor (MAF) is, the MAF looks like a honey comb on the inside. When the tube is off and the car is off, ask someone to sit in the car and see if if you throttle body is opening and closing while the other person is pressing the gas. If not make sure the cable on the side are connected. If not reconnect them and try again. Hopefully this is your problem. If your cables are connected your cables are moving and your throttle body aren’t you may have something broken inside of your throttle body causing your throttle not to work properly.
If your cables are connected and not moving, you will need to check your pedals and find out where the disconnection is coming from. If all of this checks out try disconnecting your battery for 10-15 minutes and reconnect it. It could just not be reading that you are pressing the gas. Finally, you can check your fuses and ensure that none of them are blown.
If you would like to have an expert take care of this for you, a qualified professional from YourMechanic can come to your location to diagnose the car’s acceleration problem and guide you through proper repairs.
Car is accelerating without pushing gas, full rev when placed in park, should I drive it home from work? 28 miles away, oceanside
ANSWER : Hi there. This issue is typically caused by a malfunction of the cruise control system or throttle control. However it can also be caused by something as simple as the carpet or floor mats pressing down on the accelerator accidentally. If you start your car and the throttle continues to accelerate, I would highly recommend not driving the vehicle home; as it’s unsafe to drive. I would double check the floor mat to make sure that’s not the problem and start the car to see if the issue continues. If it does not, drive home careful and get the car to a mechanic as soon as possible.
Car almost stalled, steering wheel locked up, all lights on dashboard came on, pushed gas pedal and nothing happened.
ANSWER : Hi there. When the engine is stalling and sputtering, this is an indication that the fuel system has lost pressure. Check the fuel pump relay and see if it is hot and if its clicking on when the key is turned on. If the relay is hot when the engine stalls or sputters, then there is an issue with the wiring to and from the fuel pump or the fuel pump maybe weak. For the steering column to lock up, the locking solenoid in the steering column losing power when the engine stalls. This could be an issue with the ignition switch as the solenoid is energized with the key turning in the ’ON’ position. The shaking could be either the brake rotors are worn causing the shaking when the brakes are applied or if the brakes are not applied, then the CV Shafts could have a joint that is felt when loaded when coasting. I suggest checking out the rotors, CV Shafts, the fuel pump relay, and the ignition switch. If you need further assistance with your engine stalling, shaking, and sputtering, then seek out a professional, such as one from Your Mechanic, to help you.
