To some extent, a faulty carbon canister can affect the vehicle's power, but it won't hinder normal operation. However, a damaged carbon canister should be replaced promptly, as it can lead to increased pollutant emissions. A broken carbon canister may cause a gasoline smell inside the car or around the vehicle. If the carbon canister is damaged, the adsorbed fuel vapors inside will be directly released into the air, resulting in a strong gasoline odor in or around the car. The purpose of the carbon canister is to reduce vehicle emissions and improve fuel efficiency, so its failure does not significantly impact the car's power.

As a seasoned commuter driver with 10 years of experience, I've encountered situations where the carbon canister failed, and it really caused a noticeable drop in power. The carbon canister is designed to capture evaporated gasoline vapors from the fuel tank, preventing them from being directly released into the air and polluting the environment. If it malfunctions, excessive vapors can leak into the engine, disrupting the normal fuel-to-air ratio, which worsens engine performance. Acceleration feels sluggish, especially when going uphill or during rapid acceleration, with a noticeable lack of power. Fuel consumption also inexplicably increases, and the car feels sluggish while driving. When I took it for repairs and replaced the carbon canister, the power was restored, making driving much easier. This issue isn't a major one, and repairs aren't expensive, but delaying it could damage other emission components. I recommend that owners get their cars checked at a professional shop as soon as they notice unstable idling or reduced power to avoid issues during long-distance driving.

Can the Car Windshield Be Repaired?

For small dents on the car windshield, specialized glass repair agents can be used for filling and repair. However, if the crack is large or long, repair is not recommended as the effect will be limited, and it is advisable to replace the glass directly. Steps for repairing small dents: 1. Clean the area to be repaired with alcohol and glass cleaner, and after drying, remove any possible impurities in the crack; 2. Attach an observation board to the inside of the windshield for clearer visibility during repair; 3. Align the center point of the suction cup base with the position to be repaired and secure the four corners; 4. Fix the pressurizing device to the suction cup base, ensuring correct positioning, then unscrew the upper part of the pressurizing rod; 5. Pour the repair liquid into the opening at the top of the pressurizing device and screw the pressurizing rod back into the base; 6. Wait for the repair liquid to penetrate and solidify (about 10 minutes), then unscrew the pressurizing rod, wait for one minute, and screw it back to remove air inside the crack; 7. Remove the repair device and scrape off any residual repair liquid with a blade.

Does Stage 1 Tuning Affect the Car?

Stage 1 tuning has certain effects on the car. After stage 1 tuning, the car has higher requirements for fuel quality. The gasoline used must be of higher quality, as using low-quality gasoline after tuning can cause damage to the car to some extent. During engine operation, the temperature requirements also become more stringent. If the engine's cooling system is not particularly excellent, it can affect the engine's lifespan, potentially shortening its service life. Stage 1 tuning refers to enhancing the car's performance by modifying the ECU software parameters without altering the hardware. Specifically, it involves adjusting engine parameters, mainly including fuel injection and ignition timing, to improve engine power.
