I have a 2006 trailblazer that occasionally sputters and the check engine light comes on.
My 2006 trailblazer only has 60333 miles on it. I keep up with maintance. Plugs belts idler
pully stuff like that. Last winter I started it was running like it was a cylinder down or
something. I turn it off and back on, it went away. Yesterday I drove it 6 miles, at the end
of the trip, it did the same thing. Rpms were under 500 @ idle and the moter was running
ruff. Turned it off and back on runs fine. Any ideas?
