What Causes Engine Power Loss?

[DeAngela]

Here are the specific reasons for engine power loss: 1. Intake manifold air leak: Leaks cause excessively lean air-fuel mixture. 2. Low fuel pressure: Clogged fuel injectors or fuel filters result in insufficient fuel injection or delayed fuel delivery. 3. Faulty throttle position sensor signal: Malfunctioning signals from mass airflow sensors, manifold absolute pressure sensors, or throttle position sensors lead to inadequate fuel injection. 4. Faulty sensor signals: Incorrect sensor signals cause improper ignition timing, resulting in delayed ignition. 5. Faulty ignition components: Weak spark due to defective spark plugs, ignition coils or high-tension wires.
