Will the Corolla's engine shake after prolonged use?

Corolla's engine will shake after prolonged use. Engine knocking: When the heat value of the spark plug is too high, its heat collection and dissipation time becomes faster, and the temperature of the spark plug will be lower, which can easily lead to engine knocking symptoms, further affecting the car's acceleration capability. In this case, it is necessary to replace the spark plug with a new one. If the engine still knocks, it may be due to a mismatch in the spark plug model. Engine shaking: If the heat value of the spark plug does not match, it can cause the engine to misfire, leading to abnormal engine shaking or reduced power. There are many reasons for abnormal engine shaking, and apart from a mismatch in spark plug heat value, severe carbon buildup is also one of the causes. However, the key symptom of engine shaking caused by incorrect spark plug heat value is a regular shaking of the engine when the car is idling, which can be clearly felt when holding the steering wheel.
After driving a Corolla for a long time, will the engine shake? I've been driving my Corolla for seven or eight years, and I feel it's quite durable overall, not prone to problems. But after driving for a long time, say over 100,000 kilometers, the engine might occasionally shake a bit, especially when idling at a stop or during the moment of acceleration from a standstill. Common causes could be aging spark plugs or too much carbon buildup, leading to poor ignition; or a dirty air filter affecting the air intake balance; also, loose engine mounts can make the whole car shake. My car had this issue once, and cleaning the throttle body and replacing the spark plugs fixed it. It's recommended to maintain the car on schedule, such as checking the ignition system and cleaning carbon deposits every 20,000 kilometers, which can prevent shaking. At the same time, this is also related to fuel consumption—if shaking occurs frequently, fuel consumption might increase. A money-saving tip is to avoid prolonged idling and use better quality engine oil.
I've indeed experienced engine shaking issues with my Corolla after prolonged use. As a daily commuter, it ran smoothly for the first few years, but around the 5-6 year mark, I noticed slight vibrations when idling. This is mostly caused by uneven internal engine load distribution, such as carbon buildup in fuel injectors or sensor deviations. I make it a habit to regularly check engine oil and air filters, ensuring proper oil change intervals to reduce vibration frequency. Ignoring this issue long-term may accelerate part wear and increase maintenance costs. Another relevant factor is driving habits – I prefer gentle acceleration to avoid sudden throttle inputs, which helps prolong engine life and maintain smooth operation. Overall, shaking doesn't necessarily indicate serious problems; early detection and maintenance keep the Corolla a reliable vehicle.
