Do yourself a favour here, these are a bear for DIY.
Just pay a shop to do this because even though your codes may indicate which circuit or bank, two of the four for my engine for example, share the SAME location code which means Either or BOTH could be bad.
PLUS if you think you can just swap them out to until you find the bad one, the act of putting a good one on the same circuit as a bad one can make your new one fail on testing.
Been there, done that, got a dirty Tshirt to prove it.
