What Causes a Car to Lose Power, Jerk, and Then Stall?
2 Answers
Here is an analysis of the reasons why a car may lose power, jerk, and then stall: 1. Transmission internal issues: This situation is usually caused by not changing the transmission oil for a long time. Manual transmission oil also needs regular replacement, typically every 60,000 kilometers. If the transmission is dirty, it can cause oil pressure problems, leading to jerking. In this case, replacing the transmission oil will solve the issue. 2. Fuel quality issues: This problem often occurs after refueling at a different gas station, mainly due to poor fuel quality, which leads to incomplete combustion in the engine and affects power. In this situation, switching to higher-quality fuel will resolve the problem.
I've been driving for decades and have seen many such cases. When a car can't accelerate, jerks and eventually stalls, it's often due to fuel system issues. For example, the fuel pump may have stopped working, or the fuel filter might be severely clogged, causing insufficient fuel supply. The engine needs adequate fuel for combustion - just like a person running on empty, lack of fuel leads to power loss, jerking and stalling. It could also be impurities blocking the fuel injectors, causing uneven fuel injection. When this happens, don't force it - first check if the fuel cap is loose or if the fuel filter needs replacement. If the problem persists, immediately have a professional mechanic thoroughly inspect the fuel system to prevent roadside breakdowns. This issue commonly occurs in poorly maintained vehicles, especially those using low-quality fuel long-term.
