i did my own injectors in a 96 stroke and used the kit from rosewood and had great results. but as the other guys have said please have them flowed by a shop to at least check to see if they are good. i had on that would dump fuel at idle and that would be bad news if i would've just popped them in after the rebuild. should be close to $300 for them to be flowed. good luck and they are very easy to do. follow the directions and find a internal parts breakdown diagram and you won't have any trouble rebuilding them.
