I have a 1999 Chevy malibu with a 2.4 liter engine. A little over a month ago my husband was driving it down the road from home and all of a sudden it died. He said it was almost like it totally shut off. It wouldn't start and hasn't started since then. Him and a few friends lifted the hood to take a look at it and noticed that one of the spark plugs tip was broke. One of his friends said that it might be the timing chain. I guess what my question is is... what would/could be the problem because we are not made out of money and we can't take it into a shop and we can't junk it because we are still making payments on it for another 3 months. So please can some one give advice that knows about vehicles because I do not want to fix one problem just to have it ending up being a different problem.
