Why does my geo barley go when i put it in gear, I have to rev it up for it to go

Hello, does the engine rev freely without transmission engagement? Does the engine bog down when depressing the accelerator? Need more information. But more than that, all we can give is some guesses and theory. See a local shop near you to have hands on evaluation that will clearly get you answers.
