Affected Component

Engine

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems
•Allow the engine to cool before performing inspections

Symptoms

•Knocking noise increases with acceleration
•Potential vibration felt through the floorboard
•Engine misfire or rough running
•Decreased power during acceleration
•Unusual smells, such as burning oil or coolant

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any potential engine codes
2
Perform a visual inspection of the engine and transmission mounts for signs of wear or damage
3
Check fluid levels (engine oil, transmission fluid) to ensure they are at appropriate levels and in good condition
4
Inspect suspension components for any signs of damage or wear, including bushings, control arms, and struts
5
Listen for sounds while revving the engine in neutral to determine if the noise originates from the engine or transmission
6
Perform a road test under controlled conditions to replicate the noise and observe any accompanying symptoms

Solution
