Question about 2004 GMC Envoy
Have a 2004 GMC ENVOY XL and I have similiar issues with a loud air sound when I start the suv but mine does not seem to stop after a few minutes and seems to get louder when I go up hills etc. The serive engine soon light has now come on and stays on. I am afraid to drive the envoy. Please help!!
Sounds like you may have a plugged cat. you need to find out what code/s you are throwing...

If there is an engine code po410 you have problems with your airpump. There are bulletins out on this situation.
