I doubt the computer is lying.
Low cylinder contribution is still considered a misfire.

Shop must be broken. Suggest replace with a smarter shop.

I'll suggest to begin with a compression test.

Update on P0301 misfire cyliner 1, compression check good, adjusted valves and it still comes back. Another shop "we don't know what to do with it" Maybe it is time to go back to domestic cars!

Re: P0301

Just because a shop or two can't solve the problem does not mean the problem is unsolvable. You just haven't found the person that CAN fix it yet.

Reality: Solving problems and fixing cars is not what generates the most revenue in a typical shop.
Thus, finding someone that can actually solve your problems may be rather tough if you don't know how to find that person.

Post the freeze frame data please.
