Ok. It's a '98 vw beetle with a brand new battery and 3/4 tank of gas.
We lost power- one battery cable was very loose so we tightened it. Car would then start but idle with very low RPM and would immediately die if you hit the gas. After a few days of sitting, the engine won't fire and the engine seems to shake the whole car and sputter. We were told that it might be bad gas so we bought dry gas and put it in the tank today---didn't work. Could it be spark plugs? Fuel filter? Something else?
Thanks in advance for your help!!!!!!!!!!!!!
