What if Toyota Camry accidentally catches fire and can't see the data stream?

1, check the ignition system spark plug; When the engine is idling, press the tip of the screwdriver on the cylinder head or the metal shell of the engine itself, and touch each spark plug thread with the metal part of the screwdriver. If the engine slows down gradually, the spark plug works normally. If the engine speed is unchanged, the spark plug is faulty or the compression of the engine itself is not ideal. Check the condition of the spark plug, and check the combustion chamber for oil stains or carbon deposits. 2. If the spark plug is in good condition and the engine is still turned off, it may be caused by dents at the power-off point or excessive ablation. A dent through the cut-off point indicates that the dispenser has lost its function. The causes of occasional fire generally include: the engine idle motor is stuck; The wire sleeve of idling motor is somewhat worn; Idle air hole is too dirty; There is something wrong with the engine throttle position sensor; There is a problem with the camshaft position sensor or crankshaft position sensor; Engine speed sensor is faulty or too dirty; There is a problem with the idle speed control program of the engine electronic control unit. In addition, if there is a problem with the quality of gasoline, it will also cause this failure. hope this helps
