Customer states check engine light on. Install SOP part. P0411 sec. air flow incorrect. Traced fault to a restriction in the cylinder head. No cylinder head available. TAC sent engine. Went to replace the engine. Went to replace engine. Had old one out when I found out TAC had sent the wrong engine. Called TAC again and they instructed me on how to clean air ports in head. Cleaned sec air injector ports then reinstalled engine. Verified fix.
That was my last week or two. How you doin’?
