Intermittent failure to accellerate

I May and in December I pressed the accelerator and the car failed to respond and after a couple of minutes it did accelerate

My car has 80000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
This may be a result of a couple of different things, but is most commonly associated with a faulty throttle position sensor. The throttle position sensor monitors the throttle position of the throttle plate inside the throttle body in relation to your foot position on the gas pedal. Based upon the inputs from the sensor reading your foot’s position on the pedal, the ECU then makes the direction to supply more or less fuel to the motor. When this sensor is not working properly, this can cause intermittent responses when pressing the gas pedal. I would suggest having a professional from Your Mechanic come to you home to diagnose and inspect your vehicle.

How to Identify and Fix Common car Problems ?

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.
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.
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.
The most common cause of poor engine airflow is a clogged or damaged air filter. The air filter in your car protects the engine by catching all kinds of debris before it can enter the cylinder and cause more damage.
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.
If the filter is clogged, it may not allow enough air to flow in, leading to problems with acceleration. This may also make it hard for the vehicle to gain speed when at higher miles per hour as well. That is because the wrong air-to-fuel mixture is sent to the combustion chambers to burn.
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.
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.
If the jerking occurs while pressing the brake pedal, it`s likely that you have an ABS sensor failure or that your front brakes pads are worn out and need to be replaced. It`s also possible that your front wheel bearings are wearing out and would require replacement as well.
There are a range of reasons why your car is juddering when you accelerate. Your vehicle could have dirty fuel injectors, a damaged fuel pump, a blocked catalytic converter, a faulty mass airflow sensor, broken spark plugs, or even an accumulation of moisture.
6. Surging, Lurching or Jumping – Along with the other common symptoms of a bad CVT transmission, surging can be a sign of contaminated transmission fluid. When your transmission becomes too polluted or filled with debris over time, your vehicle might begin to accelerate, jerk, lurch.
Defective Fuel Pump: The fuel pump pulls the fuel from the gas tank to the engine via the fuel lines. If the pump stops working, malfunctions, or becomes clogged, it will not supply enough fuel to the injectors. This can cause the vehicle to accelerate slowly, or even sputter and stall, especially at high speeds.

Hi I have this dtc:P0698 description (failure of wiring and connection. failure of spark plug control module) engin no start
ANSWER : Hi there. Typically this is a failure in the ignition control circuit. Most of the time it is a wiring failure going to the ignition coils such as a bad ground connection. It can also be caused by a failure in the main computer which happens most of the time on this vehicle.

I usually start by checking the circuit for power to eliminate a blown fuse or ignition switch issue. If no problems are found there then I move on to testing the wiring and the computer to see which one the vehicle needs.

My Accord gives out a "Charging system failure" warning. I drove home about 15 miles and then parked my car. After about 3 hours,
ANSWER : Hi there. On a new Honda Accord, the Charging System Failure warning light typically indicates a problem with the battery, alternator or other component inside the charging system of your vehicle. However, with less than 10,000 miles, this is most likely an electrical glitch or stored error code that was triggered. Since your car is "new", I would recommend contacting your Honda dealership first, to tell them about this warning light and ask them how they wish to handle this issue; as it should be covered under warranty. If they can’t help you, please set up a warning light inspection, and one of our mobile mechanics can come to your location and determine why this light came on.

Charging System Failure and Battery Light on
ANSWER : Hi There,
It sounds like you may have a voltage regulator issue that might not be allowing the alternator to charge the battery sufficiently. The voltage regulator could be allowing the alternator to supply too much or too little amperage to the battery resulting in the battery never maintaining a consistent charge as it is designed to. The voltage regulator is a unit that regulates the charging of the battery by the alternator. When the voltage regulator is not working properly, this may result in the alternator allowing too much power to be delivered to the battery resulting in damaging wires and prematurely sometimes destroying the battery. A common sign of this is usually the acid inside the battery boiling causing the battery to swell. You may also smell a bit of smoke due to things potentially getting too hot. In other cases it may result in the alternator not supplying enough power to the battery, resulting in undercharging the battery or not charging it at all. I would recommend having an expert from YourMechanic come to your location to diagnose your vehicle’s charging system.

Steering wheel shakes, light came on power steering assist failure 2010 Ford Escape
ANSWER : Hi there – this behavior, sometimes called "phantom steering shake" is often due to a steering torque sensor in the steering column. This device sense how much effort is being put into the steering wheel to make a turn. This determines how much "power assist" the electronic steering adds to your own effort to turn the steering wheel. If you are getting the "shake" while idling and still, this can be the beginnings of failure of this sensor. I would first go back to Ford to discuss the Recall (#14V284000), because this appears to be precisely the problem you are having. Escalate to Ford Customer Service. If this is unsuccessful, I recommend a steering wheel shakes inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, confirm this diagnosis, and give you an accurate assessment of damage and cost estimate for repairs.

Car headlight intermittently on/off even after new bulb
ANSWER : An intermittent headlight issue is a common problem. The most likely cause are the headlight assembly itself, a wiring issue, or a faulty switch. Any of these have the potential to cause the headlight to intermittently fail. If the headlight assembly is cracked or shows signs of condensation, then the assembly is most likely the issue. A qualified technician, such as one from YourMechanic, will be able to diagnose the headlight fault and perform any repairs required.
