I was driving the car. Al of a sudden the engine started shaking and making noise. When the car was to make a turn the engine stalled. The computer code said misfire in first cylinder. I replaced the spark plug. Everything was fine for a few hours. After that the engine started shaking again and the car stalled. When I looked on the new spark plug I installed, the tip was bent in. The computer code again is first cylinder misfire. Could You please help me with the information. Thank you.

Hi there,

make sure that the correct spark plug is used, there are some special "long reach"plugs used and if you have fitted one of these the piston could strike the plug. But this would happen on the first compression, so just make sure that it is set (gap) correctly and see what happens. The only other way it can happen is the piston travel is excessive and anything that can cause that will make a loud engine knock.
