Greetings all. I am new here.Ii just inherited a 2004 Tahoe LT from my brother. It was in the shop for a check engine light and they said it is the MAF. The dealer wants around $450.00 for the repair. I do believe that i can change this out myself for alot less money. I do some of my own work on my cars so it cannot be that difficult. I would like to know where do you all buy quality parts for your vehicles? Do you go online somewhere? Have any of you done this before? I am used to my Durango so this is a different beast all together. Thanks in advance!!
