Good morning.

Lead code?? please explain and can you tell me the code number?

As far as the miss there are many possibilities.

1. spark plug.
2. ignition wire, cap or rotor.
3. fuel injector or wiring.
4. vacuum leak at intake manifold.
5. low compression from internal engine.
6. valve train not moving.
