I changed my spark plugs because it was suggested by a friend who is a mechanic to start off, but my vehicle continue to randomly misfire from the OBD tool and is sounding horribly louder than it was before.

Good evening,

Do you have any codes set?

I would start by checking the fuel pressure. Low fuel pressure will cause this issue.
