I had P0172, AZ read it generically, and then a good local Indie nailed it via a specific menu/sub menu and replaced the exhaust camshaft sensor...

Rather than throwing parts, fiddling with MAF/DISA, get it read and then chase the part(s) repair.

Thanks for the input. You got it all wrong here. DISA and MAF was already replaced. Not because of this issue.
