    Throttle body cleaning for 2014 Tahoe LT

    I want to clean my own throttle body, I feel like it’s pretty easy to do. But I’ve seen some guy on YouTube with a third GEN Tahoe that had to use a computer to reset the RPMs at idle after cleaning it. Is this so? And what’s your guys experience cleaning them? I feel like I’m losing power...
