toyota engine misfire
Hello everyone, friends, in this video of a Toyota Avalon with a malfunction, one candle does not work for us, I put it on a working coil with a candle, I have a good half-burning and damped vibrations of the coil, and when I put it on a non-working candle, the oscilloscope shows us like this, the car is in at the moment it trips and with each trip the oscilloscope signal is distorted and this method can determine a faulty spark plug, but it does not show misfires on cars because of this it is very difficult to diagnose without an oscilloscope and only with it you can determine the cause of a non-working spark plug or by replacing all spark plugs, but here you can clearly see how the signal is distorted due to the spark plug, and after replacing the spark plug, the whole problem disappeared.
