Car still works but struggles when electric assist is charging also leaks oil. Any advice is appriciated thanks !

You're not paying attention. Please refer to my first post - as I said, there are 8 plugs. They can look perfect and still not function. Unless you know they've been replaced in the last 60K miles WITH THE OE STYLE PLUGS, replace them.
I've encountered P030X misfire codes on 3X HCH2, and in all three cases, they needed new plugs.

There's also a Denso P/N but I can't find it on RockAuto, and I can't get to denso's site.
If you buy them locally, they're likely to run you $14 EACH
