Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems
•Allow the exhaust system to cool before inspecting to prevent burns

Symptoms

•Loud noise during acceleration
•Possible vibration felt through the floor or steering wheel
•Decreased acceleration performance
•Increased engine RPMs without corresponding power increase
