No this is not a problem related to a throw out bearing or a vaccum leak. This most likely is caused by dirty fuel injectors, old spark plugs and old spark plug wires. It could be a combination of these. Each is fairly easy to diagnose. I am going to change the plugs first as my 2006 Trailblazer LT EXT has 97600 miles on it with the original plugs and wires, Then I will change the wires. Last will be the fuel injection cleaning service at the dealership.
