Was wondering if anyone can help me with my problem? I replaced the head gaskets on my daughters 97 lumina. Now it runs but it loads up with fuel. it gets so bad that fuel drips out of the muffler. Anyone have any ideas where to look for this problem. I also have to hold the gas pedal to the floor in order to get it started. I havent worked on cars for atleast ten years and am not to familar with fuel injection cars. It's a 3.1 liter eng. Thanks for any help with this!! Bob
