After stopping at a red light, I put my foot on the gas pedal; however, the car only moved jerkingly after a few seconds. What can be the cause?

The most likely cause is that your car needs a tune-up. When a car's engine runs, the spark plugs create tiny explosions that power the engine. Over time, these plugs can become fouled by deposits of oil, fuel, and carbon. As a result, they may not create the strong spark needed for combustion. A tune-up involves replacing the spark plugs and other worn parts in order to restore peak performance. In addition, the engine's computer may need to be reset in order to adjust the timing and fuel mixture. If you're experiencing this problem, it's best to take your car to a mechanic for diagnosis and repair.
