The P0304 code means that cylinder #4 is misfiring or is randomly misfiring. The P0350 code means that the Powertrain Control Model (PCM) has detected a problem with the primary or secondary circuit of one or multiple ignition coils or ignition coil packs in your engine.
The P0304 code is a serious engine issue that requires immediate attention. A misfire is the absence of a full combustion event on a given cylinder as expected.
Here are some possible causes of a P0304 code:
- A faulty ignition coil, spark plug, or wire
- Loose fitting electrical connectors
- Broken or disconnected vacuum hoses
- The engine is dirty or has low oil pressure
Here are some possible causes of a P0350 code:
- A problem with the electrical circuit
- Damaged or loose connection of the spark plug wires
- A faulty PCM
The most common symptom of a misfiring engine is a loss of power. The engine may also run rough, be difficult to start, or stall completely.
Here are some repairs that can fix a P0304 code:
- Replace the spark plugs
- Replace the cap and rotor, coil pack, or plug wires
- Inspect the wires around the spark plugs for damage and loose connections
- Replace a faulty fuel injector
- Replace a worn ignition wire or a bad coil
- Repair engine mechanical issues
- Fix air leaks
- Repair fueling faults
- The P0350 code indicates that the Powertrain Control Module (PCM) has detected a malfunction in the circuit of one or more of the engine's ignition coils. The code is set when the Engine Control Module (ECM) does not receive a valid pulse signal from the ignition coil.
- Common causes of a P0350 code include:
- Faulty or shorted primary or secondary circuits
- Defective or damaged ignition coils or coil packs
- Disconnected, frayed, or otherwise faulty wiring and connectors

@waqasbajwa67 how did you check your spark plugs and your coil? Hopefully you changed your plugs….:-)

I'm not familiar with this car, but if it has individual coils for each cylinder then I'd start with replacing the coil on cylinder #4, since the other code, P0304, indicates a misfire on cylinder 4. At the very least you could try swapping #4 coil with another cylinder and see if the misfire follows it.

@awladhossain You will need to get the car scanned for whatever trouble codes are causing the check engine light to turn on. Here in the US most auto parts stores will scan your car for free, but if that's not a service provided where you live you can buy an inexpensive bluetooth OBD-II device that can be read with a free app on your phone.
Best if you start your own question and add the trouble code information when you get it.
