The check engine light will illuminate any time there is a failed EVAP system test. This will be indicated by the various on-board diagnostics trouble codes that are stored in the vehicle's memory. Also, in some models, there may be a popping sound accompanying the check engine light, as the leak detection pump continuously attempts to pressurize the fuel tank. The canister may also cause difficulty starting the engine, a rough idle, and poor fuel mileage.
When the fuel filter begins to clog, the engine suffers from fuel starvation. This will cause a significant reduction in power and may also cause a misfire. These conditions may be intermittent, or constant and worsen over time. As the issue progresses, the engine may being to stall immediately after starting, fail to start, hesitate under throttle, or stall at particular angles on hills.

A fuel tank leak may also cause difficulty starting the engine, a rough idle, and poor fuel mileage. When a fuel tank is simply corroded to the point of failure, the exterior tank condition rarely shows damage. The inside of the fuel tank will be rusted or corroded, and rust flakes or other debris may be floating in the fuel.
When faced with a gas smell in your Mercury Mystique, it's crucial to adopt a methodical diagnostic approach to identify and resolve the issue safely. Start by inspecting the fuel system for visible leaks, particularly around the fuel injectors and carburetor, as these areas are common sources of fuel odor. If you notice dampness or stains, it may indicate a leak that requires immediate attention. Next, check the condition of the O2 sensor and coolant sensor, as these components can significantly impact engine performance and fuel efficiency. A malfunctioning O2 sensor can lead to improper fuel mixture, while a faulty coolant sensor may disrupt the engine management system. Additionally, assess the air filter and air inlet for blockages, as restricted airflow can exacerbate fuel smell and affect mileage. If the Check Engine Light is illuminated, consider cleaning the EGR valve and its passage to ensure proper exhaust flow. Remember, addressing these issues promptly not only enhances your vehicle's performance but also mitigates the risk of fire hazards associated with fuel leaks. Always prioritize safety by working in a well-ventilated area and wearing appropriate protective gear.
When you detect a gas smell in your Mercury Mystique, it's essential to investigate the underlying causes to ensure safety and proper vehicle function. One of the most common issues is a loose fuel cap, which can lead to fuel vapors escaping. Additionally, overfilling the gas tank can cause fuel to spill into the EVAP system, resulting in noticeable odors. It's crucial to check for any hidden leaks in the fuel lines or connections, as these can pose serious health risks and fire hazards. Other potential culprits include a malfunctioning O2 sensor, which can disrupt the engine's air-fuel mixture, or leaky fuel injectors that may allow fuel to escape where it shouldn't. A dirty air filter or restricted air inlet can also contribute to engine performance issues, leading to gas smells. In some cases, the odor may be linked to the brake system, particularly if it occurs during heavy braking or stop-and-go traffic. Inspecting brake pads and the clutch for wear can help identify if the smell is related to braking components. By systematically checking these areas, you can pinpoint the source of the gas smell and take appropriate action to resolve the issue.
If your Mercury Mystique emits a gasoline odor, it’s crucial to act swiftly, as this could indicate serious underlying issues that pose safety risks. Start by checking the gas cap, as a loose or damaged cap can allow fuel vapors to escape, leading to unpleasant smells. If the gas cap is secure, inspect the fuel system components for leaks, including the fuel filler hose, filter, and lines. A strong gasoline smell may suggest a leak, which not only increases the risk of fire but also exposes you to harmful fumes. Additionally, consider the possibility of a vacuum leak, which can create a lean condition that contributes to the fuel smell. Ignoring these symptoms can lead to significant damage to your vehicle and jeopardize your safety, so it’s essential to address any issues promptly. By taking these steps, you can ensure a safer driving experience and maintain the integrity of your Mercury Mystique.
