2. Faulty fuel injector: A faulty fuel injector can prevent fuel from being properly injected into the engine, leading to reduced power. Have the injectors cleaned or replaced if they are faulty.
3. Intake manifold gasket leak: An intake manifold gasket leak can cause vacuum leaks, which lead to reduced engine power. Check the intake manifold gasket for leaks and replace it if it fails.
4. Exhaust system blockage: A blocked exhaust system can restrict the flow of exhaust gases, reducing engine power. Inspect the exhaust system for blockages and clean or repair as necessary.
5. Catalytic converter failure: A failed catalytic converter can clog and restrict exhaust flow, reducing engine performance. Check the catalytic converter and replace it if it fails.
6. Worn spark plugs: Worn spark plugs can result in incomplete combustion, reducing engine power. Replace spark plugs according to the manufacturer's recommended intervals.
7. Faulty ignition coil: A faulty ignition coil can cause weak or intermittent spark, leading to reduced engine power. Have the ignition coil checked and replaced if faulty.
8. Incorrect ignition timing: Incorrect ignition timing can cause poor combustion and reduced engine performance. Have the ignition timing checked and adjusted if necessary.
9. Faulty oxygen sensor: A faulty oxygen sensor can lead to incorrect air-fuel mixture, resulting in reduced engine power and increased emissions. Replace the oxygen sensor if it fails.
10. Engine mechanical issues: Internal engine issues such as worn piston rings, damaged cylinders, or excessive bearing clearances can lead to reduced engine power. Have the engine inspected by a qualified mechanic to check for internal issues.
