Problem overview

Some Mazda 3 owners report experiencing engine drops when the vehicle is put in gear, which can indicate several underlying issues that require attention. These problems may stem from issues with the shift linkage or cables, leading to difficulties in shifting gears or an inability to shift altogether. Additionally, a defective throttle position sensor can cause reduced engine performance, resulting in engine jerks, RPM fluctuations while idling, and a gradual drop in speed after releasing the accelerator. Furthermore, problems with engine mounts, such as tears, cracks, or fluid leaks, can also affect performance. To address these concerns, owners are advised to have the shift linkage and cables inspected, check the throttle position sensor for defects, and examine the engine mounts for any signs of damage. Prompt resolution of these issues is crucial to prevent further damage and ensure the smooth operation of the Mazda 3. If problems persist, consulting a professional mechanic or authorized Mazda service center is recommended for a thorough diagnosis and repair.
