Do another scope test but this time do all cylinders stacked together then a comparison can be made. Please get your camera angled correctly as videos the wrong way up are difficult to assessComment

If you are using the SIA 2000 adapter you should be able to see all the cylinders firing. I think you should have a selection for True or Waste. If it doesn't you may be seeing samples of both, so waste spark usually a lower kv and since the spent gases be rushing out an open exhaust valve , that might be the turbulence you see, which be normal. Maybe if that Mazda truck is using a Ford DPFE sensor, check KOEO voltage should be only about 1 volt if you are going after the EGR code.Comment
