What Causes a Car to Lose Power When Accelerating with AC On?

[DamianAnn]

When a car loses power while accelerating with the air conditioning on, it may be due to the following reasons: 1. Engine misfire, leading to increased fuel consumption, black smoke emission, poor acceleration, and severe vibration. 2. Clutch slippage, causing improper gear engagement or disengagement. 3. Low fuel rail pressure. 4. Dirty throttle position sensor or voltage imbalance resulting in electronic throttle failure. 5. Issues with the air filter: If components like the air filter or throttle body are clogged or malfunctioning, causing insufficient air intake, the car may experience sluggish acceleration and jerky movements. 6. Problems with the spark plugs: If the spark plugs exhibit poor ignition, leakage, or atomization issues, it can also affect the engine's acceleration performance.
