it be? I can smell fuel when pressing the gas. Had someone look at spark plugs and they said it's fine. Checked battery too just in case. Could it be a coil? Also, when trying to start car the engine block shakes up and down about two inches. Possible engine mount broken but not have confirmed. Would that cause it, or will that just cause rough running. When car died it seemed to not be gettin fuel..like would go then feel like pullin back. Then when it actually died car shook pretty badly. Engine coolant overflow line is not hooked up any longer, heard thats not something that could cause it though. Oil cap was off on car for short drive. Could that have done something to engine?
