Ignition coil broken will have what symptom

Core tip: one is in the idle state, the body jitter is obvious. Observe the exhaust port, the car has obvious intermittent exhaust from air, the exhaust pipe at the same time jitter, able to clearly hear the voice of 'getting'. It is in the idle state, body jitter is obvious. Observe the exhaust port, the car has obvious intermittent exhaust from air, the exhaust pipe at the same time jitter, able to clearly hear the voice of 'getting'. The second is in the process of driving, in 2500 the revolution speed, body has obvious jitter, to accelerate the weakness; After the speed of more than 2500 turn, shaking feeling disappear. 3 it is to open the hood, observe the running engine, found that the engine has obvious shaking. The jitter has obviously does not belong to the normal engine working condition of jitter, dither amplitude is very large. If only one ignition coil fails, the remaining three cylinder works, barely emergency driving is not a problem, but the car engine, frame and connecting parts are very bad. A baolai designated service mechanics teacher recommended temporarily stop using short cylinder vehicle, if more than one cylinder ignition coil burned, advice immediately stopped.
