Why does my car suddenly lose power while driving?
by
The most likely issue is a clogged fuel filter. The purpose of the fuel filter is to ensure that dirt and debris stay out of the fuel system, so over time, it may need cleaned or replaced. When the fuel filter is clogged, the fuel pump has to work much harder, resulting in a far less efficient drive.
What causes Dodge Durango to shut off while driving?
Common reasons for this to happen:
Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine.
Why does my Dodge Durango feel sluggish?
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.

What causes loss of power during acceleration?
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.
Why does my car feel slow and sluggish?
Why Does My Car Have Sluggish Acceleration? Faulty sensors: bad oxygen sensor, crankshaft sensor, MAF sensor, Camshaft Position sensor, or any sensor relative to the EFI system.
Why does my car feel like its lacking power?
The most likely issue is that a component is clogged. A clogged fuel filter is the most common reason, although a loss of power in your car could also indicate problems with the fuel pump or fuel line. Impurities or debris may be blocking the system, which causes the loss of power in a car.
Why do I feel like my car isn’t going as fast?
One of the most common reasons for poor acceleration is a problem with your car’s air intake system. If there is something blocking the air flow into your engine, it will prevent your car from getting the oxygen it needs to create the combustion needed for acceleration.
Why does my car feel like its lagging when I accelerate?
A common cause is a problem with the spark plugs or ignition system. Other potential causes include a blockage in the fuel line, a faulty oxygen sensor, or a problem with the mass air flow sensor. Vacuum leakages can also cause a delay in acceleration. A clogged air filter or low engine oil level can also be a cause.
What are the signs your transmission is going out?
What Are the Transmission Failure Symptoms?
Refusal to Switch Gears. If your vehicle refuses or struggles to change gears, you are more than likely facing a problem with your transmission system.
Burning Smell.
Noises When in Neutral.
Slipping Gears.
Dragging Clutch.
Leaking Fluid.
Check Engine Light.
Grinding or Shaking.
How does a car act when the transmission is going out?
Grinding, Jerking, or Shaking
Shaking and jerking are good indicators of transmission trouble. Gear grinding is a common symptom in manual transmission vehicles. Automatic transmission failure often begins with some hesitation during gears shifting. Some might describe this a “slipping,” as well.
What are the signs you need a new fuel pump?
Seven Signs Your Fuel Pump Is Going Out
Sputtering Engine. Your fuel pump is telling you something if your engine starts to sputter once you’ve hit the top speed on the highway.
Overheating Engine.
Low Fuel Pressure.
Power Loss.
Surging Engine.
Gas Mileage Decrease.
Dead Engine.
What are signs of a clogged fuel filter?
HOW DO YOU KNOW IF YOU’RE DRIVING WITH A CLOGGED FUEL FILTER?
You have a hard time starting car. If the problem is the fuel filter, and it isn’t changed soon, you may find that your vehicle won’t start at all.
A bad fuel pump may overheat and inadequately deliver gas to the engine, causing it to run hot and turn off while on the road. In this scenario, your vehicle may start back up after overheating and shutting down, only to do the same thing a half-hour later. This scenario is a common sign of a bad fuel pump.
What happens when fuel pump goes out while driving?
The engine surges while driving.
This is caused by too much fuel being sent to the engine. When that happens, you’ll notice your engine surging—the vehicle will repeatedly pick up speed and then drop speed, even though you haven’t touched the gas pedal or the brake.
What are the signs of failing fuel pump?
Six Signs of a Failing Fuel Pump
The importance of fuel pumps. Fuel pumps inject gasoline from the fuel tank into the engine in most cars and trucks.
Engine Sputtering at High Speeds.
Decreased Fuel Pressure.
Losing Power when the Vehicle is under Stress.
Inability to accelerate.
Decreasing Gas Mileage.
Engine Not Starting.
What are the symptoms of a failing high pressure fuel pump?
Symptoms of a high-pressure fuel pump failure are:
Delayed start of the engine.
Hesitation or sputtering in acceleration between 2000 RPM to 4000 RPM.
High engine temperatures.
Vehicle stalling due to exertion or temperature.
Fuel pressure gauge reading low measurements.
Poor gas mileage.
How can I test my fuel pump?
How do I reset my fuel pump?
The fuel pump shut-off switch has a red reset button on top of it.
Should your vehicle shut off after a crash, you may restart your vehicle:
Switch off the ignition.
Switch to start position.
Switch off the ignition.
Switch on the ignition to re-enable the fuel pump.
If vehicle does not start, repeat steps 1 through 4.
Can a fuel pump be weak but still work?
A weak fuel pump may still pump fuel, but the vehicle may experience difficulty starting from the lack of pressure. A weakened fuel pump can cause the vehicle to take more cranks to start than normal, and in more serious cases may even cause the vehicle to require multiple turns of the key before it will start.
