Engine code help

Not sure where to post this, but anyone know what these codes are ?

p0301 - Misfire on cylinder 1
P0003 - Misread in the Fuel Volume sensor (could be a short, corrosion, or fuel regulator going bad)
P03AA - Pressure low on Cylinder 3 aka misfire
The last one I have no idea, but based on a misfire code I got on a bad spark plug on Cylinder 2 I got other codes that appeared separate but were actually sensors freaking out because of the misfire

So a little update, I had done a firmware update on the JB4 and the codes have since disappeared along with the car driving well again, I had brought it to the dealer and they said maybe bad gas

Did they give you any warranty grief about the JB4?

 

[Boogioogi]

They didn't mention anything about my jb4 or the methanol

Ok, good to know, thanks’

Where you able to fix all the codes? Or did the dealership fixed it all under warranty?

The codes were fixed after the update and haven't come back since. It's I also been about 10,000 km since and the car still drives like new.
