My niece had a similar problem with a similar vehicle.And it turned out that it was the engine knock censor that had failed. The dealer found the problem but by then the engine had been damaged and they replaced it for free under warranty.

You live in my area. I live in a small town 30 miles west of Springfield. Just out of curiosity, what shop did you send her to?
My wife and I have seen enough Lifetime movies to know not to hire a 19 year old nanny. Lol
Small world. I haven’t referred her to a shop / she didn’t ask. She lives an hour southeast of Springfield with her family so assume she’ll end up at a shop there. But if I were to recommend a shop, I’d probably refer her to Ken Owen first. And then maybe to Aasby’s.
Where would you send her/someone first?

I know this is "closed", but getting multiple misfires and a P0300 - is almost never coils or plugs. I see people, including shops - immediately throw money away putting on new coils and plugs. If your insistent on doing that, swap just one - so when it doesn't go away you haven't wasted more.
I agree with the timing chain as likely issue - both cam sensors being over-advanced.

Which if it happens enough, she should have no job.
I get your interest in the situation and helping her, but some people need to think for themselves and not always rely on others for help. Better for her to learn that lesson being a 19 year old nanny, than when she is 35 with 3 kids and loses her job.
I've heard good things about Kenny Owens but have not used him. I've heard good things about Eaglecrest Automotive in Nixa and have several friends that use them.
I use a place close to where I live if I need anything done but I do most of my own work so I rarely take my vehicles anywhere.
It sounds like she lives fairly close to where my ex-wife lives. My son and his wife also live there.
With all those codes I'd first do a compression test before throwing plugs/coils/injectors/vvt solenoids at it. Also check the oil, low oil will set those kinds of timing codes, if the level is good and compression checks out (at least 158psi) then the solenoids are probably clogged up.
The p0420 is likely due to misfires, the cat may be fine if you caught it early but if they've been driving around a long time like that it might be cooked. If the plugs and coils are shot that's also the likely reason the O2 sensor is stuck rich.
