Causes of a Car won’t Accelerate Symptoms

It is hard for a driver to notice acceleration problems with normal driving. With circumstance like driving up a hill or during fast driving, it is in these situations a driver will notice the slow acceleration meaning the engine of their vehicle struggles to keep up. For high mileage vehicles, the symptoms will be seen immediately.

It’s a common problem to high mileage vehicles, but it’s not that serious or requirement of immediate attention regarding the engine as some need to be checked first to locate the problem then possibly fix it. Stated below are some of the common causes in this article.

Oxygen Sensor Malfunction

car engine partsExhausts emissions are monitored by the oxygen sensor device, air-fuel ratio going through the engine of the vehicle are analyzed by the monitoring of the device. Acceleration and smooth running required will be achieved when the car gets the proper amount of fuel, for the fuel to burn properly in the combustion cylinders.

The computer unit receives information about the amount of fuel being used from the sensor, that’s why when the sensor gets damaged there will be a result of fuel rich mixture as the engine of that vehicle will have no idea what ratio of air mixture to intake. No matter how you, the result will be slow acceleration.

Clogged Air flow meter

A car won’t accelerate when the Airflow meter malfunction. It is attached and located on the inlet air cleaner. Engine engine control unit will calculate the air-fuel mixture data received from the inlet air cleaner when the air flow meter measures air mass that flows.

Throttle position sensor fail

This sensor is to detect the throttle valve opening angle which is controlled by the gas pedal. Data is sent to the engine control unit through the detector when you accelerate. Engine speed cannot be controlled when the TPS malfunctions as there will be an increase or decrease without any press or depress of the accelerator pedal.

Dirty Fuel Filters

Clogged Air Filters

Similar to fuel filters provide clean fuel to the engine, the air filters supply the engine with clean air to be used in the air-fuel mixture which is sent to the combustion chambers to burn. Slow acceleration and decrepit will be a result if your air filter is clogged with dirt as the engine won’t get the right air-fuel mixture

Causes of Steering Hard to Turn

One common problem experienced by drivers with the steering wheel is when it becomes difficult to turn. Most cases people turn when at low speeds and this when the hard turning will be noticed. Possibilities of the power steering system having problems will be an indication of hard turning.

The system got many components like the pump, serpentine belt and the hydraulic power steering fluid which make it easier to turn without the wheel resistance as the hydraulic power fluid works against the piston. If you have any of the components have issues, then turning the steering will be not easier. In this article, you will find causes that make it hard for you when turning the wheels.

Worn-out Serpentine Belt

car power steering pumpWhen the serpentine belt is cracked or damaged, you will experience steering wheel stiffness. It gets worn down with time as its always being used when you drive the vehicle. The stiffness of the steering begins when it loosens, and if ignored it breaks altogether when you fail to replace which leads total fail of turning the steering wheel.

Bad Steering Rack

The steering rack is made up of the rack and pinion. It’s kept attached to the steering wheel with a series of U-joints and shafts. As the vehicle is in use, the rack will eventually become worn and damaged. This will be noted when you start the car and still the steering wheel remains stiff. The racks get hotter as the engine keeps running causing the lubricant to settle in more. You will need to replace before the problem escalates.

Pump Failure

The amount of pressure needed to allow the pump of the power steering produces smooth turning of the steering wheel. When the pump fails, you will experience turning the steering wheel to be difficult. Even with the fail of the pump, you will still turn the steering wheel, but a lot of force will be applied unlike when it’s in good shape.

Thick Fluid

At low speeds, you will experience stiffness as you turn the wheels. Draining the old fluid will solve the problem as you replace with entirely new fluid.

Leaky Fluid

When you don’t have enough power steering fluid, then don’t expect smooth turning of the wheel. Most cases the fluid will be on low levels as it leaks from the pressurized hose area. It usually gets loose or cracks causing the leakage. The steering wheel becomes stiff as the pump won’t produce enough pressure due to inadequate lubrication in the system.
