[McRhett]

The causes and solutions for engine acceleration noise are as follows: 1. Aging or loosening of engine mounts. Solution: Tighten or replace the engine mounts. 2. Improper use of engine oil quality. Solution: Use the engine oil grade specified in the vehicle manual and avoid mixing different brands of engine oil. 3. Engine misfire. Solution: Inspect the working condition of each ignition coil and cylinder spark plug. 4. Drawbacks of direct fuel injection. Solution: Install engine sound insulation padding to reduce noise. 5. Timing gear noise. Solution: Tighten or lubricate the timing belt and replace damaged gears. 6. Engine carbon buildup. Solution: Clean the throttle body or drive at high speeds to remove carbon deposits.
