We have a 2010 Tahoe with around 65,000 miles that has been babied. A few months ago, error codes P0172 and P0175 starting showing up. I figured replacing the O2 sensors wouldn't help, but I ordered them anyway, but I haven't installed them yet. Today, P1516 (throttle actuator control module and position performance) popped up, and the truck went into reduced power.

I'll check out the TAC connector and wires tonight, but we're heading out of town for the Wednesday before Thanksgiving, so I need to get this fixed fast. Should I go ahead and purchase a throttle body? Any suggestions? Thanks
