There are several reasons for this situation. Although there is oil and fire, but I can't see the car, I can't check it.
I can only give you some reasons for the fire. First, the most serious reason is that the head gasket is not installed correctly, resulting in insufficient cylinder pressure and misfire. The solution is to remove the spark plug and measure the pressure in the cylinder. Second, the cylindrical line (high voltage line) leaks electricity. On the surface there is electricity, but if there is a leak in the high voltage line, that will also cause misfires. Voltage line to detect the cylinder in turn. The third problem is the electronic fuel injection nozzle. The fuel injection is not atomized and the spark plug cannot ignite. The solution is to clean the fuel nozzle. 4. The inac enginetif is blocked and inactive. Solution
Remove it, clean it, or replace it. 5. The computer block has an error code. Find the connection point and clear the error code. Simplest step by step method to try the above method. I haven't seen the car.
I can only tell you this
No, it will cause spark plug problems and ignition system problems.
1. Spark plug problem: The spark plug may have high pressure and misfire for reasons such as excessive life or dirt.
2. Ignition line problem: Ignition line failure or poor contact will cause high voltage failure and the line must be inspected and repaired.
