The knock sensor is in most cases a ghost code for another code

Clearing does nothing for fixing the issue. It erases vital info for diaging it.

Never clear a code till the problem is identified and repaired.

Mass air flow code will not cause issue. The crank sensor controls injector pulsing issue

How did you test the crank sensor?

Not the distributor. Just spark
