noticed a cracking sound coming from the engine, and saw that there’s something causing an arc. It’s not consistent or in a particular location. Anyone seen something like this before? I’ve attached a video, really couldn’t pin down the exact location. Seemed to be happening in a few different spots. Couldn’t find any exposed wires or any abrasions in nearby wires/harnesses. Bad coil boots maybe?

Also it seemed to completely stop doing that after about 5-10 minutes or so
