I just cant figure it out

[Class_D]

So I got my Tahoe back from the Dealer and man do I appreciate the work they do. All this time I thought it was my upper intake, well actually it was lower intake. They also informed me that my waterpump was leaking and the rear seal on my tranny was leaking...after a little under $2 grand, I'm glad my Tahoe is running like a Champ!
