How to Deal with Misfire in a 4-Cylinder Engine?

[OKaylee]

Misfire in a 4-cylinder engine refers to the phenomenon where the cylinder fails to ignite during operation or cannot achieve effective pressure due to incomplete combustion after ignition. The following methods can be used to address misfire in a 4-cylinder engine: 1. Check whether the cylinder pressure in each cylinder is normal. Typically, the cylinder pressure in a vehicle should be around 1300 kPa. If it is abnormal, the cylinder with abnormal pressure should be addressed. 2. Inspect the spark plug's firing condition, the size of the free gap, and whether there are cracks in the ceramic area. Replace any damaged spark plugs. 3. Check whether the timing marks on the timing belt or timing chain align correctly. If there is an error, disassemble the timing mechanism and realign the timing marks.
