Mazda 3 classic liner soft? Please answer deliberately.

1. What you said about the sinking of the rear wheel lining does exist. However, it can be handled. Use a special "S" hook, and fix the inner liner with AB glue on the inner side of the metal end face of the rear fender rim, which can be handled in the shop. 2. The throttle opening is affected by the temperature, and the engine water temperature needs to be preheated. The throttle body water pipe is used for preheating.
