What are the symptoms of a faulty igniter?
3 Answers
The symptoms of a faulty igniter are: 1. When the vehicle is idling, the body shakes noticeably. Observing the exhaust pipe outlet, the exhaust gas flow shows obvious intermittency, accompanied by severe exhaust pipe vibration and clearly audible popping sounds; 2. During driving, when the engine speed is below 2500 rpm, the vehicle body exhibits significant shaking with poor acceleration. The shaking disappears when the speed exceeds 2500 rpm; 3. The running engine shows obvious vibration that significantly exceeds normal operational vibration levels, with large amplitude shaking. An igniter refers to a device capable of providing sufficient energy instantaneously to ignite pulverized coal or oil fuel and maintain stable flame. In automobiles, the igniter refers to the ignition coil.
Last time when my car's ignition system had issues, the symptoms were quite obvious: the engine kept cranking but wouldn't start during ignition, just buzzing without firing up; the car shook violently when driving, like it had Parkinson's; power delivery was sluggish when accelerating, lacking strength for climbing hills; it would occasionally stall at intersections, which was really nerve-wracking. The dashboard warning lights were blinking glaringly, and fuel consumption inexplicably increased. The technician told me that delaying repairs would damage the spark plugs and catalytic converter, making repairs more expensive. Now whenever I notice any ignition irregularities, I immediately go to the shop for inspection. Developing a habit of regular ignition system maintenance is really beneficial.
Having driven for most of my life, ignition failures are nothing new. Symptoms usually include difficulty starting, requiring multiple turns of the key; rough idling with the engine panting like an old ox pulling a cart; sluggish acceleration with no punch; and the constant illumination of the warning light as an alert. If left unattended, the engine may start emitting black smoke and suffer from poor thermal efficiency. I encountered this a few times when I was younger, and timely replacement of the ignition coil always solved the problem—it's not costly but prevents major disasters. During regular maintenance, pay attention to the cleanliness of the ignition system, such as ensuring spark plugs and wire connections are free of dust buildup, to minimize trouble. Remember, small issues left unattended can turn into major problems—fixing them early saves both peace of mind and money.
