Hello and welcome to the forum! What are the codes that keep popping up? Have you replaced the MAF?

It's very possible your intake boots are ripped, causing these error codes.
Check out this tech article: Air Intake Ducts Replacement

I'd probably simple and start with checking the intake ducts for tears, since it doesn't cost you money. If there aren't any rips or tears in any of the boots, I'd probably do a MAF cleaning. If that doesn't work, maybe a replacement MAF.
