There might be some vacuum leaks from deteriorated hoes, so check those.

Look around on-line and you can find good deals. There is a site called, thefind. Com that is very good at locating parts from reputable companies. But buyer beware, some companies that are selling the part for a to good to be true price or from a company that you never heard of, just avoid.
