California restricted - not certified for California emissions
Problems:
Misfire
Engine misfires can occur due to faulty spark plugs, ignition coils, or fuel injectors, leading to rough idling and poor performance.
Catalytic converter failure
Emission systems in California-restricted vehicles are complex and prone to issues, especially if not maintained properly. This can lead to a failure in the catalytic converter, which is crucial for meeting stringent emission standards.
Oxygen sensor failure
Oxygen sensors can fail over time, causing incorrect air-fuel mixture readings and resulting in poor fuel economy and increased emissions.
Egr valve issues
The Exhaust Gas Recirculation (EGR) valve can become clogged or malfunction, leading to increased emissions and poor engine performance.
Vacuum leaks
Vacuum leaks can cause unmetered air to enter the engine, leading to rough idling, stalling, and increased emissions.
Fuel pump failure
A failing fuel pump can result in poor fuel delivery, causing the engine to run lean, misfire, or even stall.
Evap system issues
The Evaporative Emission Control (EVAP) system is designed to prevent fuel vapors from escaping into the atmosphere. Faults in this system can trigger the Check Engine Light and lead to increased emissions.
