Only one cylinder of spark plugs was disassembled, and the master said that it was easy to cause problems when removing the spark plug first. When I entered, I had already returned the old engine oil, but I didn’t see how much it was. Everyone take a look at whether there is a problem with my spark plug? How to solve it?
