How to Identify and Fix Common car Problems ?

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.
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.
What Does the Automatic Transmission/Automatic Gearbox Warning Light Mean? The automatic transmission warning light means there`s an issue with the transmission, possibly the fluid temperature, fluid level, or pressure.
Automatics. Automatic vehicles use what`s called a torque converter to manage transmission fluid and keep your engine running while at a stop. If your torque converter fails, the engine can stall out.
Some of the most common sensors that lead to engine stalling include the mass airflow sensor (MAF), engine coolant temperature sensor (ECT) and manifold absolute pressure sesnsor (MAP). The idle air control valve (IAC) and exhaust gas recirculation valve (EGR) are also well known for causing engine stalling.
A clogged fuel or air filter can make your engine sputter and your acceleration lag because the engine is not getting enough fuel or air, respectively. The combustion chamber needs the correct amount of air and fuel in order to generate combustion efficiently.
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.
Yes, transmission problems can cause your check engine light to come on. Your automobile`s main computer, the engine control module (ECM), talks with system sensors to make sure everything is okay. If the transmission sensors report a problem, the ECM will turn on the check engine light.
Some common symptoms of a failing transmission include unusual noises, slipping, grinding, and jerking when engaging and shifting gears. A failing transmission can lead to various issues ranging from your vehicle making loud noises, behaving erratically on the road, or being undrivable.
There are a large number of reasons why your car might stall while driving. It could be a dead alternator, a bad coolant sensor or lack of fuel, just to name a few. Is your car stalling while accelerating? If so, then it could be a major vacuum leak, clogged fuel filter or a bad fuel pump.
The most common reason is simply running out of gas. However, if you have a full tank of fuel, and your car still dies, then there is more to it than a lack of gas. You might have a clogged filter or a bad fuel pump, for example. Both of these issues prevent your engine from getting enough fuel.
In vehicles with automatic transmissions that sometimes have a problem with stalling at lights or stop signs, most of the time it is a difference in pressure on each side of the pressure plate. A loss of pressure on one side or another will cause a stall.
Issues with the sensor system of the motor:
If one of the sensors is defective or provides wrong values, a may result in a bad fuel mixture. This can cause the car shuts off while idling.
Engine Speed Sensor — This measures the RPMs of the engine and plays an important part in making the sure the engine is running efficiently.
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.
Faulty spark plugs result in an engine misfire due to incomplete burning fuel. An interrupted combustion process can significantly affect the engine performance. Unattended engine misfire may result in intermittent strange engine sounds, power loss, and engine knock.
What could the problem be? 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.
A sputtering engine is a sign of a lean fuel mixture in the combustion chamber. This can happen if you have a clogged somewhere in the fuel system that impedes the delivery of fuel into the chamber. For example, your fuel filter or fuel lines might be clogged.
Ford F 150 jerk on acceleration can be caused by an oil pan gasket, which may need to be replaced. Ford F 150 jerk on acceleration can also be caused by a faulty throttle positioning sensor. If the vehicle jerks when accelerating, this will cause an increase in fuel consumption and may need to be replaced.
When the level of transmission fluid goes down, you will get a warning light on the dashboard. The warning light indicates hotter temperatures than normal of the fluid, and there is a need to get the fluid checked.
Transmission light usually flashes due to overheating. If the fluid is low, it is possible for the transmission to overheat. Depending on how much it overheats, the remaining fluid can be pushed out of the vent tube. Low fluid levels and overheating will cause internal transmission damage.
Maintain Proper Transmission Fluid Levels
The #1 cause of transmission failure is low fluid, which causes overheating. In automatic transmissions, it causes delayed engagement, harsh shifts, and slippage.
A car has two speed sensors: the ISS and the OSS, working together to show the transmission data to the car`s powertrain module. The ISS sensor monitors the input shaft`s speed. If these sensors get misaligned, the operation of the transmission system will be affected.
Typically, two sensors communicate the transmission data to the vehicle`s powertrain control module. The first sensor, referred to as the input sensor, monitors the speed of the transmission`s input shaft. The second sensor is the output sensor, which monitors the output shaft speed.
