Sorry for the late response, I should probably be checking this forum a lot more often lol.

It has, the only code currently triggering is p0410 - Secondary Air Intake.

I have explored the forum a little bit and found that quite often this code triggers as a result of faulty soldering in the RCM. That one could be tricky because I don't know a whole lot about how cars work and especially not their electrical, I do have the PDF that was posted on how to fix it but I'm still not entirely sure I want to be mucking around with it.

As for my original issue, I had to order some bits online because I couldn't find a 5 point Torx Security bit anywhere in my area (Scarborough) to take out the MAF for cleaning.

Once I try cleaning that I'll see what/if any other symptoms described continue, due to how long it's been going on, I may have to replace the MAF sensor though.
