Either the cam sensor is going out, or you might have a timing issue. Have the vehicle hooked up to a scan tool so they can read your cam retard/timing.

So, everyone agrees that I should take it in and have it diagnosed. I was affraid of that. Is there anything I can check with my multi-meter?

Looks like the main tool for this DTC diagnosis is gonna be a Tech 2 scan tool that the dealer has.
