My 2002 chevy trailblazer struggles too much.?

[Leandro]

in the morning, even if I warmed it for 10 minutes, I roll out my lot and I hear like a lot of "air", you know like a vacuum cleaner that makes a lot of noise but does not vacuum?
the rpm goes a bit high it seems and takes just a bit too long to get in the next gear, (it's an automatic of course!), i just had tune up too any ideas?

spray brake cleaner on engine while its running will idle high if you have a vacuum leak thats what it sound like, and check your trans fluid while trans is at running temperature and in neutral and add fluid as needed keep car running while you check the fluid
