If a car jerks while driving, this is a strong sign of engine trouble. It could be caused by a spark plug malfunction, clogged fuel lines or fuel filter, a glitch in the vehicle's computer or from many other issues, according to HowStuffWorks. Regular oil changes and other preventative measures help to keep this from happening.Know More
Cars often jerk when accelerating, after being left outside in cold, rainy temperatures. This is the result of moisture building up in the distributor cap, which produces an uneven electrical current, and the engine misfires. Leaving a car in a garage before rainy weather helps to prevent this from happening.
If a car begins to jerk more frequently over time, this could be from a vacuum leak in the fuel system.
If a car jerks all the time, regardless of temperature, a faulty throttle position sensor could be the culprit.
A car can also pull, which is similar to a jerk but is more gradual and is typically to one side. Like a jerk, a pull can be caused by a variety of issues, including the alignment, uneven tire pressures, putting a new tire into the rotation with the old tires, a torque steer or a problem with the brakes, if the pull only happens when applying them.Learn more about Car Parts & Maintenance
Some of the most common causes for a car's stalling whilst driving include: a poor idle speed control, or ISC, system, low fuel pressure, loss of ignition and vacuum or EGR leaks. Diagnosing the specific problem should be a priority in order to get it fixed.Full Answer >
A car shakes while driving because of problems with the suspension or wheels that cause these elements to not sit properly and therefore shudder as the vehicle moves forward. Shuddering often intensifies the faster the vehicle moves. Shaking and tremors occur in the steering wheel as vehicles reach higher velocities.Full Answer >
There are various reasons why vehicles shake while accelerating and some of them include a clogged transmission filter, a worn-out universal joint and low transmission fluid. The common type of vibration is mainly felt through the steering wheel of the car as it accelerates, and it is a very dangerous condition because it can cause unstable conditions that can lead to loss of control especially when avoiding a collision or making a sudden turn.Full Answer >
Moisture in the distributor cap can cause a car to jerk when accelerating. When a car has been parked overnight in cold temperatures, moisture can form inside the distributor cap, causing the engine to misfire when accelerating. A misfire occurs because the engine power is off balance or uneven. Parking a vehicle in a garage or a warmer environment helps prevent moisture from forming.Full Answer >
