Your friend is almost right.... but since you would have most surely had the
battey disconnected during the swap, the KAM would have been cleared quite
some time ago.... FWIW, on yours, learned strategy would pretty much be
limited to fuel trims.
I'm thinking that you have two concerns... for the oil pressure, the only
way to be sure is to check the oil pressure with a master gauge... recreate
the conditions where your pressure drops.
For the check engine light.... all I can suggest is (at the very least)
having memory codes scanned... A better bet is to have the quick test
performed including KOER if necessary....

one busy man to another.... ask for what you need, not for what you want...
