ISO: A good, decent priced mechanic with a shop! I have a 2006 Chevy Cobalt. Whenever I put gas in my car I have to rev the engine for a few minutes to get the gas flowing or else it just shuts off after I crank it. I only have this problem when I put gas in so therefore my husband and I are pretty sure it's related to the gas tank. But, I really need it hooked up to the computer so I can figure out what's wrong with it. TIA!
