Hi everyone. I was just inspecting a spark plug from cylinder 1 and I checked it, it looked perfectly fine and okay. I put it back in and the engine starts to misfire and it says it’s misfiring. I took out the spark plug again and it I believe a part of it broke, not the actual spark plug but I saw white stuff particles on the crusher washer. I put a new spark plug in there and started the vehicle and now it started misfiring and knocking and now I have no idea what to do. My last thing I’m going to try to do is vacuum out the spark plug hole because I believe some debris got in there and that’s what’s causing the misfire and knocking. The new spark plug I put in was an E3.81 one.
The vehicle is in perfect running condition before I inspected and removed the spark plug. After I removed it, then started misfiring.
If anyone has any suggestions or advice, please let me know what I should do from here. I was just tinkering around and I guess it led to this tragedy. The vehicle is a 2017 Mazda CX-5 2.0L 4 Cylinder
Well what you want to do is pray you just damaged the ignition coil that goes on top of the spark plug so replace that. Because if it's not that something fell in the hole when you took the spark plug out and damage the piston
