Can a faulty valve in the Tiggo 3 cause shaking?

Yes, a faulty valve in the Tiggo 3 can cause shaking, and the engine will vibrate. The function of the car valve is specifically responsible for introducing air into the engine and expelling the exhaust gases after combustion. In terms of engine structure, valves are divided into intake valves and exhaust valves. The intake valve's role is to draw air into the engine to mix with fuel for combustion; the exhaust valve's role is to expel the burned exhaust gases and dissipate heat. Taking the 2020 Chery Tiggo 3 as an example, it is a compact SUV with body dimensions of 4420mm in length, 1760mm in width, and 1670mm in height, a wheelbase of 2510mm, and a minimum ground clearance of 190mm.
I've encountered many Tiggo 3 owners asking this question, and indeed, faulty valves can cause engine vibration. Valves act like the engine's breathing gates. When they malfunction—such as having poor sealing or becoming deformed—it can prevent a cylinder from working properly, leading to uneven engine operation, especially noticeable during idling or at low speeds. This issue may also be accompanied by symptoms like poor acceleration and a sudden spike in fuel consumption. In severe cases, it can cause cylinder misfires, significantly impacting the driving experience. The Tiggo 3's engine design is generally reliable, but prolonged lack of maintenance or the use of low-quality fuel can easily lead to such problems. I recommend first checking the malfunction indicator lamp (MIL). If it's constantly lit, it might indicate a valve issue. Even if it's not lit, don't ignore the problem. It's best to visit a professional repair shop to scan for diagnostic trouble codes (DTCs) to determine whether the issue lies with the spark plugs, ignition system, or valves. Addressing it promptly can prevent minor issues from escalating into major ones.
