so the XK8 has developed an intermittent rough running and misfire issue. it's been happening during every journey for the last couple of weeks, throwing up a restricted performance fault.
I have been through the diagnostics and believe it to be a misfire on cylinder No3, so this a video about how I go about fixing the issue.
