Why can't the car accelerate beyond 80 km/h?

[GabrielaMarie]

Possible reasons why the car can't accelerate beyond 80 km/h are as follows: 1. Engine air filter: A faulty air filter can cause poor air intake, leading to a significant drop in power. You can remove the air filter and test the power without it. 2. Fuel filter: A clogged fuel filter can result in poor fuel supply and insufficient fuel pressure at the injectors, causing a noticeable loss of power. 3. Exhaust blockage: Another reason for power loss could be poor exhaust flow. This issue often occurs in winter when the car is driven only short distances (3-5 km) and turned off before the exhaust pipe heats up. Water can accumulate in the exhaust pipe, freeze in cold weather, and gradually form larger ice blocks that eventually block the exhaust pipe, reducing power. If completely blocked, the car may not start. The solution is to heat the exhaust pipe until the ice melts.
