There are numerous reasons a car stutters when accelerating, including vacuum leaks, wiring issues and faulty sensors, according to AutoHub 360. In some cases, bad weather can cause this problem. When the engine is cold, moisture can collect on the distributor cap and cause the electrical current to the engine to misfire. When a car stutters during acceleration, it is a symptom of an underlying engine issue.Know More
A common reason a car stutters is the result of a vacuum leak, AutoHub 360 suggests. This type of leak develops over time and occurs when fuel or air enters the car’s engine. A stutter occurs when combustion in the engine is disproportionate. Clogged or dirty fuel injectors also can cause a car to stutter by preventing fuel from properly entering the engine.
Electrical or wiring issues can cause cars to stutter. This type of problem happens when electrical parts and wires are worn or loose. Loose wires and defective electrical components cause short circuits in the transmission or engine, which causes the car to stutter when accelerating.
A faulty throttle sensor is another common cause of a car stutter. When the driver presses the gas pedal, a malfunctioning throttle sensor doesn't send information to the engine computer properly and this causes the car to stutter.
Regardless of the reason the car stutters, it's important to repair the issue before it causes serious damage to the engine, AutoHub 360 recommends.Learn more about Car Parts & Maintenance
If a car shakes when it is idling, the cause is usually something happening with the engine, such as needing new spark plugs. The spark plugs provide an electrical arc that ignites the gasoline vapor in the vehicle to push the piston and provide power to move the car down the road. Even though the vehicle is just idling, it takes power to keep the engine running smoothly.Full Answer >

A car can hesitate or stall while going uphill for a number of reasons, but typically the problem occurs when the engine's valves and rings are worn. Because driving uphill puts the engine under additional stress, less compression is dispensed, which weakens the engine over time. Stalling can also occur when the engine's sensor no longer works.Full Answer >
