I'd look for a problem with the EGR system, the airflow sensor (MAF), and the intake ducting for air leaks. There isn't much info in your question and I don't have much specific advice for you, I recommend you find a GM specialist to help you. If you want to find a specialist, here's a directory link for you: https://repairpal.com/directory?address=37062&car_brand_names=GMC
