Hi,

Have you checked to make sure there are no vacuum leaks? Something may have been disconnected when you replaced it. Also, what was happening prior to the replacement that prompted you to replace it?

Take a look through this link and see if it helps:

Let me know if that helps and if you checked for leaks.

Take care,
Joe
