I bought a 88 mustang for my first car and I can't figure out what's wrong with it. Being a girl, I don't know very much about cars, some but not all, and my dad doesn't always have the time to help me. When I first got it, it had a brand new motor put in it. My dad and I cleaned out the gas tank, and it starts. But when we put it in drive it bogs down and wants to die. I just need to know some ideas of what could be wrong with it. Thanks in advance!
