GMC ENVOY NOISE PROBLEM

2006 GMC Envoy • 134,000 miles

My envoy idles like its going to die when you first start it but then runs just fines, its not making any other noises or doing anything else unusual and runs great, could it be bad spark plugs? Also my stabilitrack and service stabilitrack lights come on but when I shut it off and restart it they go out why is that?
