What is the P0304 Code?
The P0304 code is a diagnostic trouble code (DTC) that indicates a misfire in cylinder 4 of your engine. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors the performance of your vehicle's engine and emissions system.
Key Points:

- Part of OBD-II: Monitors engine performance and emissions.
Common Causes of P0304 Code
Understanding the potential causes of the P0304 code can help you diagnose the issue more effectively. Here are some common reasons for this code:
- Faulty Spark Plug: A worn or damaged spark plug can lead to incomplete combustion, causing a misfire.
- Ignition Coil Issues: If the ignition coil for cylinder 4 is malfunctioning, it can prevent the spark plug from firing properly.
- Fuel Injector Problems: A clogged or faulty fuel injector can disrupt the fuel supply to cylinder 4, leading to a misfire.
- Vacuum Leaks: Leaks in the intake manifold or vacuum hoses can cause an imbalance in the air-fuel mixture.
- Engine Mechanical Issues: Problems such as low compression or valve issues can also lead to misfires.
Symptoms of P0304 Code
When the P0304 code is triggered, you may notice several symptoms, including:
- Rough Idling: The engine may shake or vibrate while idling.
- Decreased Power: You may experience a loss of power during acceleration.
- Check Engine Light: The check engine light will illuminate on your dashboard.
- Poor Fuel Economy: A misfire can lead to increased fuel consumption.
How to Diagnose and Fix P0304 Code
Diagnosing the P0304 code involves a systematic approach. Here are the steps you can take:
- Check for Other Codes: Use an OBD-II scanner to check for additional trouble codes that may provide more context.
- Inspect Spark Plugs and Ignition Coils: Examine the spark plugs and ignition coils for wear or damage.
- Test Fuel Injectors: Ensure that the fuel injector for cylinder 4 is functioning correctly.
- Look for Vacuum Leaks: Inspect the intake manifold and vacuum hoses for any signs of leaks.
- Perform a Compression Test: Check the compression in cylinder 4 to rule out mechanical issues.
Example of a Simple Fix:
If you find that the spark plug is worn, replacing it may resolve the P0304 code. However, if the issue persists, further investigation into the ignition coil or fuel injector may be necessary.
