You, obviously, do not know a goddamn thing about cars. Before you start replacing stuff, buy a book, look stuff up on the internet, go to the "gasp" library and check out a few books,
www.howstuffworks.com will help, and figure out what you're looking at.
Next, if you need the car immediately, take it to a shop and let them fix it. Since you're unsure whether the car is fuel injected or carbureted, there's a 95% chance that whatever you do will not help the car in any way. This is just a fact, don't think I'm trying to insult you. Maybe you have some friends you can call to see if they can come give you a a hand with it? (preferably ones who do know a lil' somethin' about cars)
