What’s the problem with the jitter when the car starts hot and cold?
Reader Miss Wu asked: When the car is started in cold or hot, there will be jitters. What is the problem?
Reply: The main problem of vehicle jitter occurs in the ignition system. The ignition coil is the part that stores energy, and the spark plug is the part that releases energy. The two must be well coordinated. If the spark plug is faulty, the energy is released. If you don’t go out, the ignition coil will be broken down, so check the working condition of the spark plug.
