Thanks for letting me join your group. I bought this Tahoe about 10 years ago, it was one of those certified, pasturized, homonigized, sifted, blended, stired an shaken vehicles from a GM dealer. It now has about 84000 in it, we have put probably 40000 of those on in the last 10 years. I has been an awesome vehicle for us. It is now having some small problems, so I joined your group hopeing that someone else can give me and idea on how to fix it. Thanks again.
