Check firing order
The main reason a car misfires is because the spark plug wires are not installed correctly. Check the car's firing order to ensure the spark plug wires running from the distributor cap to the spark plugs (in the cylinders) are in the right order. One or more spark plugs could be damaged or worn so the firing order is correct, but the spark plugs are not sparking into the spark plug wires to ignite the engine.
