The reason is, that air has already been accounted for and the fuel trim has been determined, but if that air is released and not immediately reintroduced to be read, you have a dead spot in the fuel trim and nowhere for that fuel to go but to either run you rich, or puddle up in the intake and cause predetonation off of compression stroke, and backfire then in turn burn the next strokes fuel during the back fire, and then in turn again leaving you in a now lean condition.. Boom knock goes up, intake temps rise, not enough fuel to compensate and then burnt up pistons/ring lands..or even worse cracking a piston due to extreme heating then cooling( 1300+*F down to 500+\-*f )in the matter of fractions of a second expanding and contracting the metal to fast to be able to rebound and thus weakening and cracking or shattering them..Sent from my iPhone</blockquote>
