What is the reason why the van suddenly cannot accelerate?

The reasons why the van suddenly cannot accelerate are: 1. No gasoline; 2. The three-way catalytic converter is blocked, and you can go to a regular enterprise for three-way catalytic cleaning; 3. Insufficient cylinder pressure; 4. During driving, sometimes the car may suddenly fail to accelerate due to bumps. A van is a general term for vehicles that have no protruding engine compartment or luggage compartment at the front and rear, resembling a loaf of bread. Its shape is mainly rectangular, different from sedans, with more internal seats and larger space. The doors are 3 to 5 in total, with one door each for the driver and the front passenger seat. The rear cabin mostly has 1 to 2 sliding side doors, with a few having no sliding side doors. The rear luggage compartment has one door. Compared to sedans, vans can carry more passengers and cargo.
I've encountered the issue of the van suddenly losing power several times, especially during long-distance deliveries. The vehicle would gradually lose strength while driving, and it felt like pressing the accelerator had no effect. There are several common causes for this: First, problems with the fuel system, such as an abnormal fuel pump or a clogged fuel line due to dirt, preventing fuel from reaching the engine. Second, faults in the air system, like a dirty air filter or leaks in the intake pipe, leading to insufficient air supply and poor fuel combustion in the engine. Third, issues with the ignition system, such as worn-out spark plugs or faulty ignition coils, making it hard to start the engine. I've also noticed that sometimes it's a fuel quality problem—using the wrong fuel or having water mixed in can cause this too. It's important to check the air filter before driving to avoid such sudden breakdowns, as safety comes first, especially since stalling on the highway is extremely dangerous.
