Diablo, Have you done your timing belt?
If not, it's very important that you get this done, either do it yourself or don't drive the car untill it's done.
Don't cheap out on the timing belt either. Oem parts are the way to go. www.prostreetonline.com
has a deal where you get oem timing belt, water pump, tensioner and return spring for $140 or somthing. Otherwise the shops will be putting in autozone's "duralast water pump and duralast $15 timing belts" in your car (drualast is just an autozone product).
