I have a 2005 PT Cruiser. I was low on gas and in a hurry the other morning so I went to the nearest corner store and put 10.00 dollars in until I could get to a gas station that cosand put only half of can in itt less so I could fill it up. Everything was fine, or so I thought! About an hour later, my car started bucking like and the my engine light came on. Came home and read mt car book. Which said it was probably water in my fuel line. Was told to buy additive I then was told to put 10.00 of a high octane gas in and add the remainder of the additive, which I did. Then removed the negative cable from battery so it would reset my illuminated engine light. I thought again it was OK. About 3 hours later I ran to the store and it started spitting and jerking, and the light came back on... HELP, HELP PLEASE
