Okay so i have a 1988 Mustang Convertible 5.0 GT. Well ive had plenty of problems out of it. First, the idle is horrible. It idles up and down and then shuts off. Mostly happens at red lights. I turned the idle up just to stop it from dieing but problem is still there. What might be the problem there? Someone said vaccum leak but i don't know. It is also burning a lot of oil. It was really low and i just put three quarts in and now it won't stay started and it's choking on me. It also sounds like it's flooding. Im getting so upset here because it's just something right after another. Help me!!
