Rough acceleration on my Trailblazer I6

[agustincorrea]

Gents, does some one know if there is adjustment for better acceleration on my 6 cyl. 2004 trailblazer LS? I had a 2005 Trailblazer same model from Enterprise Rent a car and it really fly on the road. Mine feels like a 4 cyl. I checked the tire pressure which is at 35 PSI but also noted that the rented one had tire size 245/75/16 and mine has 245/70/16.

Does someone knows if my SUV needs some type of adjustment? It has a new Air Filter and does not have any additional equipment. Also when I apply reverse the engines some times shakes like when its trying to turn of fand then comes back to 700 RPM again?

The first mistake was buying a car from Enterprise. My brother was a manager for them for a few years. The branches are responsible for oil changes. They get paid off of profit so they would hardly ever maintain their cars. He told me about a trailbalzer that went from Fl to Ny and back in a weekend. it was already 10,000 miles without an oilchange. The customer was complaining about it rapping. They put some rislone in it and got an oil change. Stay away from anything from Enterprise, they pound the shit out of those cars and sell them at a far inflated price. I was actually able to get my TB under the GM supplier vendor discount cheaper than Enterprise wanted to sell one with 25,000 miles on it.

GM dealers should have better deals than car rentals.

He didn't buy a TB from Enterprise. He Rented a 2005. He has a 2004.
