I have been watching your channel for a long time. I just realize that you live in the same town that I do Clarksville anyway my 2005 trailblazer LS four-wheel-drive has been in the shop for three months. Every time the guy says that he has fixed it and cleared all the codes. I pick it up and it is still doing the exact same thing. I will get it about 4 miles down the road and all of the sudden it won’t except gas I guess you could say, it just chokes completely out and dies and I have to put my flashers on and then all of the sudden it might kick in and run like a top for 30 seconds. He replaced something in the emmisions a vacuum tube and he put two new injectors on it, but I think he’s just missing the whole  Problem he has one of those several thousand dollar scanning machines. Can you give me any idea what you think it might be. Thank you so much.
