As soon as codes are erased, car idles sooooo bad for 1-2 seconds and they come up again.

What makes your friend think you did the compression test incorrectly?

Kind of hard to do it wrong. Screw it in tight, turn it over for a few seconds, and make sure it held pressure.

You could get a bore scope and check the cylinder walls/top of piston too. They're cheap on Amazon.

Did you check for a broken valve spring or bent push rod? Very common.
