The car hasn't been running great, so the plugs may reveal other issues. While that work is being done, thoughts on also replacing the coil packs? Worth it or typically a waste?
Personally I think if the coils are original with 90k, all those heat cycles take a toll on them, I would replace them just for piece of mind knowing they are new.
