Upgrading to high-performance ignition coils like Mallory or Broquet is a popular choice among car enthusiasts looking to enhance engine performance. However, this upgrade can sometimes lead to misfires and other ignition-related issues. Understanding common problems associated with ignition coils and their fixes can help you troubleshoot effectively.
Understanding Ignition Coils
Ignition coils are crucial components in an engine’s ignition system. They transform the battery’s low voltage into the high voltage needed to create a spark in the spark plugs. This spark ignites the air-fuel mixture in the engine cylinders, allowing the engine to run smoothly.
Common Ignition Coil Problems
- Misfires: One of the most common issues after upgrading coils is engine misfires, which can lead to rough idling and decreased performance.
- Hard Starting: Inconsistent spark delivery can cause difficulties in starting the engine, especially in cold weather.
- Increased Fuel Consumption: Poor ignition can lead to incomplete combustion, resulting in higher fuel usage.
- Check Engine Light: A malfunctioning ignition coil may trigger the check engine light, indicating a problem that needs attention.
Troubleshooting Misfires
If you experience misfires after upgrading to Mallory or Broquet coils, consider the following troubleshooting steps:
- Check Spark Plug Condition: Worn or fouled spark plugs can cause misfires. Inspect and replace them if necessary.
- Verify Coil Installation: Ensure that the ignition coils are installed correctly and securely. Loose connections can lead to misfires.
- Inspect Wiring and Connectors: Damaged or corroded wiring can affect the performance of ignition coils. Check for any visible damage.
- Test Coil Resistance: Use a multimeter to measure the resistance of the coils. Compare the readings to the manufacturer’s specifications.
Fixing Common Issues
Once you identify the source of the problem, you can take appropriate action to fix it. Here are some common fixes:
- Replace Spark Plugs: If the spark plugs are worn out, replacing them can resolve misfire issues.
- Reinstall Coils: If you find that the coils were improperly installed, removing and reinstalling them correctly can help.
- Repair or Replace Wires: Any damaged wiring should be repaired or replaced to ensure proper electrical flow.
- Adjust Timing: If the ignition timing is off, it can cause misfires. Make sure the timing is set according to the manufacturer’s specifications.
Preventive Measures
To avoid ignition coil problems in the future, consider these preventive measures:
- Regular Maintenance: Perform routine checks on your ignition system, including coils, spark plugs, and wiring.
- Use Quality Parts: Always opt for high-quality ignition coils and components to ensure reliability and performance.
- Monitor Engine Performance: Keep an eye on engine performance and address any issues promptly to prevent further damage.
- Consult Professionals: If you’re unsure about any aspect of your ignition system, consult a professional mechanic for advice and service.
Conclusion
Upgrading to Mallory or Broquet ignition coils can provide significant performance benefits, but they may also introduce new challenges such as misfires. By understanding common ignition coil problems and applying effective troubleshooting and fixing techniques, you can enjoy a smoother and more efficient driving experience.
