Will a car lose acceleration power when it gets too hot?

[DelJace]

Yes, a car that has become overheated can experience a loss in acceleration power. Here are the relevant explanations: 1. Ignition system failure: Aging ignition coils or spark plugs that haven't been replaced for a long time can lead to insufficient ignition energy and poor combustion. This results in weak engine acceleration and the illumination of the engine fault light; low pressure caused by fuel system malfunctions can also contribute. 2. Excessive engine carbon buildup: This can impair fuel atomization, leading to poor combustion of the air-fuel mixture, excessive exhaust emissions, and weakened engine acceleration. 3. Engine system malfunctions: These can cause the engine to enter an emergency operating mode, thereby limiting power output and resulting in poor acceleration. Examples include failures in engine sensors such as oxygen sensors, air flow meters, crankshaft position sensors, knock sensors, etc. Signal faults from these sensors can trigger the engine's emergency operation mode, slowing down acceleration.
