Why does a car experience weak acceleration after wading through water?

[AustinFitz]

The reasons for this situation include waterlogged air filter blockage, water entering the exhaust pipe, or brake pad sticking. Below are the explanations of the causes and solutions: Air filter blockage: When water enters the air filter, it causes blockage, resulting in insufficient air intake for the engine, leading to weak power and acceleration. The solution is to remove and replace the air filter. Water in the exhaust pipe: If water submerges the exhaust pipe, some may remain inside, affecting the engine's exhaust flow and consequently its power. Once the exhaust expels the water, the engine's power will return to normal. Brake pad sticking: After driving through water, the brake pads and discs may rust and stick, creating resistance during driving. If the situation is not severe, the rust can be removed by the heat generated during driving. In severe cases, new brake pads and discs need to be replaced.
