IDLES UP AND DOWN WHEN AIR IS ON

2005 GMC Envoy • 100,000 miles

My GMC Envoy idles up and down, but when I run my air its much worse, to the point that it will shut off and my air compressor clicks on and off. What is that?

The idle control system is acting up. Get the throttle body and IAC cleaned and retest.
