That's the frustrating issue with something like that, because without full diagnostic you are left with swapping out expensive parts one by one. I can't remember what my code was, but on the advice of respected impreza mechanics, I replaced nps, coil packs, and numerous sensors. I even had a Terraclean ( that WAS a waste) I was assured it couldn't be my injectors, but on testing the flow was poor, and I never looked back. I'm not suggesting that this is the op's issue, just highlighting how hard it is to track down, even with a code. However, everyone bangs on about changing spark plugs regularly, but generally ignore their injectors, which are crucial to have a good spray pattern, and will be in a **** state at above 70000 miles.
Codes are definitely a starting point though.

live data logging tells me a lot , I suppose being old school I am used to diagnostics without any computers to help,
a simple plug check can tell a lot about how an engine is running which pot to start looking for issues ect,
many "mechanics" nowadays are just part fitters, no diagnostic skills, if the computer doesn't say yes they just swap parts in a certain order, typically start with the cheapest first,
Being an electrician by trade maybe my logic/diagnostics skills are just better,
Many assume it's x or y as that's what it was for them.

I was able to use a bluetooth OBD reader and the torque app to read the code I had on my blobeye, total cost was under £10 (not sure if this cabn be used on MY2000?) Mine was a warning about emissions from the CAT, cleared code via the app and took it for a blast (had just been doing short commutes back and forward to work for weeks so suspect the cat had not been getting up to temp (no idea tbh)) and the EML never came back.
In short, read and cleared code for about £10 and fixed issue on Jap car with an Italian tune up.

can any bluetooth OBD reader off ebay do a blobeye or does it need to be a certain type?

I'd go for a descent one that connects to your phone and uses an app. Although I have a cheap ODB reader with cable cost me £15 and works perfectly.
I have a light come on my new classic, but think it's the cat and it's blowing.
Not checked it yet as goes off as soon as I drive off.

What APP would you use with an OBD reader, I don’t know anything about these , I am truly a Dinosaur lol. And where is the port you plug into, I’m guessing it’s not easily accessible lol

As it's a MY99 it is highly unlikely to be OBD compliant and will either need Subaru select monitor (SSM) or read the codes the "classic" way
