Does a loose timing chain have any impact?

[DelRuby]

Yes, it does. A loose timing chain can cause symptoms such as abnormal noises during acceleration and sudden engine stalling while driving. Here are the specific symptoms at different times: 1. During low-speed driving: Slight looseness can result in weak car performance and inability to accelerate when going uphill. 2. During fueling: The exhaust pipe may produce a popping sound. 3. During medium-speed driving: The car may experience unstable acceleration, easy stalling, unresponsive throttle, and weak acceleration while maintaining a constant speed. 4. During acceleration: The engine may produce abnormal noises, or there may be unusual sounds from the engine pulley area.
