Vehicle won’t accelerate when check engine /VCS lights are on. Also on initial cranking in the morning there’s a sound like a vacuum.

DTC P1441 SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE NO.2 BANK 1 STUCK OPEN
DTC P1444 SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE NO.2 BANK 2 STUCK OPEN

The codes are for fault with switching valves on both banks. It is possible but very unlikely for the valves to go bad at the same time. So first step is to check the secondary air pump for proper operation. The secondary air pump is located under intake manifold as shown in the illustration attached.
