I need some help!!! When I start my car it runs good at a idle when cold. Once the engine heats up the car bogs down and looses all power and some times dies. I have noticed the fuel filter was low so mabey it's a fuel issue? Also when I put it into gear the gen light comes on! So Mabey 2 issues. I checked the oil and it didn't appear to have water in it such as a blown head gasket. I do have headers do Mabey a vapor lock issue? Fuel pump? I don't know where to start
