Reasons for weak car power may include carbon deposit issues, incompatible fuel grades, clogged filters, etc. The specific details are as follows: Carbon deposit issues: Including cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, intake carbon deposits, etc. Fuel grade issues: Adding incompatible fuel grades can lead to reduced car output power and weakened performance. Alternatively, if the fuel tank vent hole is blocked, or components such as the fuel tank switch, fuel filter, and the fuel line from the tank to the carburetor are partially clogged, it may fail to supply the required amount of fuel, resulting in an overly lean air-fuel mixture and insufficient engine acceleration. Clogged filter: Long-term use of the air filter without timely cleaning can cause clogging, and insufficient air volume will lead to an overly rich combustible mixture, thereby reducing engine power.

What to do if the Chery Arrizo 5 trunk has a serious water leakage problem?

The dryness around the mat indicates that the water is entering from beneath the mat. Upon removing the trunk interior, it was found that the reserved holes near the rear bumper may be the source of the leakage. Remove the plastic cover and fold back the interior panels on both sides. Then, dismantle the mudguards of the rear wheels. To take off the rear bumper, the mudguards must be removed first. After unscrewing all the screws, check for any missed screws. You can then see the gaps in the rear bumper where it is no longer secured by screws. Clean the dust around the reserved holes. Use tape to cover the small holes from the inside, then apply sealant from the outside. Press the sealant down with the original tape. This concludes the entire process. Installing rubber pads on the small holes as sealing material can prevent such leakage issues from recurring after a few years.

How Long Can Headlight Restoration Fluid Last After Application?

After using headlight restoration fluid, the effect can last for about one month. If the headlight has very fine scratches or appears dull, headlight restoration fluid can be used to repair it, and the headlight can basically return to its original state. However, this restoration method only works for a short period of time, and after a while, the headlight cover will become dull again. More restoration methods are as follows: 1. Polishing Restoration: This method is relatively common. Simply put, it involves sanding the headlight with sandpaper and then polishing it with special wax. The effect of this restoration method is obvious, but the drawbacks are also significant—not every area can be polished, and the protective film is also sanded off. 2. Vapor Deposition Restoration: This method essentially involves reapplying a protective film. Sealant is applied to the edges of the headlight, then sanded with sandpaper, and finally, a professional tool is used to apply the protective film.
