Hi There,
This can happen for a number of reasons and should have triggered a check engine light. Some of the things that may be causing this could be a failing catalytic converter, a faulty oxygen sensor or potentially a dirty or faulty mass air flow sensor. Due to the number of possible causes for something like this, I wouldrecommend having one of our experts from YourMechanic come to your location to diagnose using a scanning tool to download any potential fault codes the computer may have stored. This will help to further narrow down what may be causing this to happen.

How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
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.
What causes weak acceleration? Dodge charger acceleration issues can be caused by a number of things. Most often it is because the gas pedal is not responding properly to the accelerator. This can be caused by low air pressure in the tires, a faulty engine, or even just a dirty throttle body.
An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
Fuel injector nozzles can become clogged over time, which can lead to a sputtering engine, slow acceleration and the car not having enough power. Fuel injectors can be cleaned if the problem is caught early, but as the conditions worsens, the injectors may have to be replaced.
The “stiff” gas pedal issue is most likely caused by a dirty throttle body in the air intake system. Cleaning the throttle body should relieve this symptom. The lack of “Drive” selection, unless first selecting “Reverse”, could be a loose or misadjusted shift cable or shift linkage issue.
Common symptoms
Throttle body and electronic throttle body issues can result in the engine stalling, failing to start, warning lights on the instrument cluster, and hesitation or power surging on acceleration.
This hesitation while accelerating can be the result of a number of issues, including something like a clogged fuel filter or even a broken fuel pump. Sometimes, something could also be wrong with the transmission.
Common reasons for this to happen:
Tire issues: The most frequent causes of a vehicle shaking while driving stem from tire issues. Tires begin to behave differently when worn or out of balance. Tire replacement, realignment, and rebalancing are common solutions.
The most common reasons a Dodge Charger has a rattling noise are the ball joints, struts or strut mount, or a problem with the sway bar links.
If you press or let up on the pedal, there will be a delay before the engine responds. This is because of the time it takes the throttle motor to activate the throttle opening. Throttle response should be nearly immediate and not delayed. Gas pedal delay is a safety defect because it can cause accidents in emergencies.
Yes. While the damage may seem small initially, the longer you drive with a bad oxygen sensor, the worse the damage will become. Eventually, you may experience rough idling, poor acceleration, engine misfires, an illuminated check engine light, and failed emission tests.
If there are no forces acting upon the object, then there is no acceleration. If there is no acceleration, then the object will move with a constant velocity.
An accelerometer sensor is a tool that measures the acceleration of any body or object in its instantaneous rest frame. It is not a coordinate acceleration. Accelerometer sensors are used in many ways, such as in many electronic devices, smartphones, and wearable devices, etc.
(1) An accelerometer is an electromechanical sensor that measures static and/or dynamic acceleration forces acting upon an object by measuring the acceleration (the rate of change of velocity) along one, two, or three axes.
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
To recalibrate the ECM and accelerator pedal, the ignition switch must be in the ON position and then the accelerator pedal must be slowly and fully depressed from idle to full throttle. Repeat the procedure three times.
In some cases a damaged throttle controller will cause the engine to have issues with acceleration or cause a “stumbling” effect when the throttle is engaged by the driver. This can result in lack of performance and can be a safety concern if not inspected and repaired quickly.
Any unusual shaking or vibrating forces coming from the engine is cause for concern. It could be something as simple as old spark plugs producing an uneven power delivery, it could be something serious like worn or broken engine mounts, or it could be even more serious in the case of internal engine damage.
#1 – Damaged Inner CV Joint
When the inner CV joint is damaged or begins to fail, you will notice your car vibrating under hard acceleration. As it gets worse, the minor vibrations turn to violent shaking when under load. Damaged CV joints usually occur because of a tear in the joint boot.
Another good indication that your spark plugs are dirty or worn is if your vehicle experiences surges of speed, resulting in a jerking acceleration. These surges occur because your spark plugs are not igniting the fuel in your engine at the proper rate, resulting in an uneven speed.
What does a bad catalytic converter sound like? Often, a clogged catalytic converter sounds like a rattling noise is coming from under your vehicle and engine when you`re starting, idling or driving. Excess heat or damage in the converter can break apart the honeycomb materials, resulting in the rattling noise.
Rattling Noise – Once your catalytic converter becomes older or damaged from fuel mixtures, the honeycombs on the inside can begin to collapse and/or break apart which will cause a rattle to occur.

So I have a hyundai sonata se push to start. My car won’t turn on, power is working, I push tof start but it won’t crank. I don’t
ANSWER : Hi there. It sounds like you have a failed starter. However, without proper testing there is no way to be 100% sure. I suggest having the battery tested first with a digital battery tester that provides current voltage, cold cranking amps, and state of health. Also inspect for corrosion on the terminals and cables as this will cause excessive resistance and not allow proper voltage/amps to the starter. Other possible failures could be in the wiring harness, relay, fuses, or communication network. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car does not start inspection.
The engine of the car runs, but when I push the gas pedal it does not accelerate, and the engine does not rev.
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. 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.
Car won’t crank when it’s cold and now won’t start at all
ANSWER : Hi there:
Usually this issue is cased by low cranking amps inside the battery. If you’ve recently had the battery replaced, it’s possible that an electrical component that makes up the charging system might be damaged or faulty. It’s also quite possible that the main electrical relay or the starter relay is giving you fits. To know for certain what the exact issue might be on your 1989 Toyota Camry, you should have a professional mobile mechanic complete a car is hard to start inspection, so they can pinpoint the source of your issues and recommend the right 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.
My car will start but won’t accelerate when I push the gas pedal. What would cause this problem?
ANSWER : I would first check to see if your Check Engine Light is illuminated. If so, there are likely trouble codes that have been stored in your vehicle’s PCM that may indicate what the problem is. In order to pull these codes, you will need an OBD-II scanner.
If you do not have one, I would recommend having your vehicle scanned for trouble codes. Once the trouble codes have been identified, the repair procedure will be more clear. It is possible that you have a fuel or ignition issue. I would recommend having these systems of the vehicle inspected as well.
If you need assistance, then consider having a certified technician, such as one from YourMechanic, determine why the car hesitates during acceleration and suggest any needed repairs.
My car ran oit of gas. I went and filled up a gas can and put it in . My car still won’t start
ANSWER : Hi there. Unfortunately, in most cases when the car runs out of gasoline, the fuel pump dries up and can be damaged. I would recommend having your car towed to your home and then have a professional mechanic come to your home and complete a car is hard to start inspection so they can determine why the car won’t start.
I pressed my gas and my car didnt accelerate. There is transmission fluid in my car and my car cranks great and runs great…
ANSWER : This kind of reaction is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. This type of problem is amplified any time the transmission is low on fluid creating a drop in hydraulic pressure. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
