my car will start then die after it gets started. it also does this funny hissing sound adter it dies. i checked all ic pipes and fuses, plugs and all. could this be vacuum? as long as you give it gas it will run but when you let off at idle it will die or if you stop without giving it gas.
please help quick this is my only car at the moment and my wife has to drive it.
