The reasons why the Jetta cannot accelerate are as follows: 1. The fuel is too dirty; the fuel injector is clogged; the fuel filter is clogged. 2. The fuel pressure regulator fails; the electric fuel pump is not working properly; the throttle position sensor is faulty. 3. The computer (ECU) fails; insufficient cylinder pressure, etc. The solutions for the Jetta not accelerating are as follows: 1. Check the fuel pump in the fuel tank to see if it is working properly; check the intake system and perform professional maintenance. 2. Check whether the gasoline grid is working properly; clean the throttle; replace with clean fuel; clean the battery frequently and replenish the electrolyte.

When reaching the end, pass the needle through the inner thread again and continue sewing. Repeat this process until the entire cover is hand-sewn.
