⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect battery before working on electrical systems.
•Allow the engine to cool down before inspecting the exhaust system.

Symptoms

•Whistling noise during acceleration
•Decreased engine performance or responsiveness
•Possible increase in fuel consumption
•Check engine light may illuminate (if related to a sensor issue)
•Air intake hiss noticeable at idle (if related to a vacuum leak)

Diagnostic Steps

1
Inspect the air intake system for any visible cracks or loose connections.
