Hey everyone, I just have registered at trailvoy and I am trying to figure everthing out here. I have a 04 Trailblazer EXT with the I6 in it, I couldn't be happier with it. I ran across this forum and found some very useful information and thought I would register. I look forward to talking to you everyone about the trailblazers and Envoys. Hopefully I can be of some help and get some help in the future, the way they make these vehicles now I think we all need help every once in a while, and it certianly is cheaper doing the work yourself.
