Faulty Spark Plugs or Wires: Worn-out spark plugs or damaged spark plug wires can cause misfires, resulting in power loss. Inspect and replace the spark plugs and wires if necessary.
Ignition Coil Failure: A faulty ignition coil can disrupt spark delivery, leading to power loss. Check the ignition coils and replace any that are damaged or malfunctioning.
Catalytic Converter Issues: A plugged or damaged catalytic converter can restrict exhaust flow and cause power loss. Inspect the catalytic converter and have it replaced if necessary.
Fuel Pump Issues: A failing fuel pump can lead to insufficient fuel pressure, causing the engine to lose power. Check fuel pressure and replace the fuel pump if it's not functioning properly.
Vacuum Leak: A vacuum leak can introduce unmeasured air into the engine, causing a lean air-fuel mixture and power loss. Check for any leaks or cracks in the vacuum hoses and repair them.
Mass Air Flow (MAF) Sensor Problems: A faulty MAF sensor can provide incorrect air flow measurements to the engine, leading to power loss. Inspect and replace the MAF sensor if necessary.
Oxygen Sensor Issues: Oxygen sensors monitor exhaust gases and provide feedback to the engine's computer. A malfunctioning oxygen sensor can provide incorrect data, affecting the air-fuel mixture and causing power loss. Check and replace the oxygen sensors if needed.
Transmission Problems: If the power loss is accompanied by transmission-related symptoms like slipping or rough shifting, it could be an issue with the transmission rather than the engine. Have the transmission inspected by a qualified mechanic.
