Misfire
Answer

Answer
this could be anything to do with the cylinder on your car. The plug, the wire, the cap, or the coil (whichever you have.) your best bet is to do a tune up on thecar and do all the plugs, wires, cap, and rotor. if you have a coil pack, try to change those. this is all i can say for now. if that doesn't work, ask the question again and give a little more detail on how the car is acting.
Technically speaking, cylinders do not "misfire": the spark plug causes a spark which causes the fuel to ignite which moves the cylinder, so it is the spark plug that may misfire. Given that, motor vehicle spark plugs may misfire due to any of a number of reasons, including watered-down or low-grade fuel, old and/or dirty oil, fouled spark plugs, clogged cylinders, insufficient oxygen to the plugs, poorly aligned cylinders, et al.
