I would change that cam sensor.Yes it would run. Also clean the maf and Throttle body. I would say with the boost gauge everywhere you have a substantial vacuum leak.

You may wish to confirm the cam interrupter magnet is still present on the cam gear. This article reviews what you should look for, and a possible way to fix it.

The proper fix is to pull the timing cover and pull the timing set. Usually a good excuse to do a timing chain job. They pretty much stop throwing the magnets at the introduction of the L27/L67, but some of the earlier units like to throw them still.
