What Causes Reduced Engine Power in Cadillac?

[Weston]

Here are the specific reasons for reduced engine power in Cadillac: 1. Clogged catalytic converter: A clogged catalytic converter can lead to poor exhaust flow, reduced power, increased fuel consumption, and in severe cases, engine shaking or even stalling. 2. Dirty air filter: A dirty air filter restricts airflow, reducing engine power and increasing fuel consumption, while also causing excessive dirt and carbon buildup in the throttle body. 3. Faulty spark plugs: Faulty spark plugs can cause rough idling, noticeable power loss, increased fuel consumption, and may lead to engine misfiring symptoms (such as backfiring, black smoke from the exhaust, and severe vibration). 4. Carbon buildup in fuel injectors: Carbon deposits in fuel injectors can result in insufficient power, rough idling, difficulty starting, and increased fuel consumption. Injector clogging is usually caused by carbon deposits from the engine or impurities in the fuel. 5. Throttle body carbon buildup: Carbon buildup is a major factor affecting throttle performance. Prolonged neglect of throttle cleaning can cause throttle opening errors and allow contaminated air into the engine cylinders, leading to abnormal engine operation.
