where can i take my truck on the southside of chicago to get a prof. tune up

The term "tune up" does not mean much anymore.....Most of the time when someone ask me for a tune up I follow up with the question..... why do you think you need one? If your truck is not running right or it has a check engine light on it would need diagnosis most likely.

miles is the man listen to him. these days everybody wants a tune up even if they mean a service of fluids.explain whats wrong with the car and symtons
