i have a vibration in my GMC Envoy when it idles and have been told that can be caused by a vacuum leak. i am currently trying to find out how to find the leak. advanced auto parts will loan you a pressure tester to try to detect the leak. i have not gotten the tester yet. would like to know where to look for it for this sort of leak before i get the tester and i am still in the process of getting that information.
