You've got a vacuum leak somewhere.

Look for the big long vacuum tube that goes along the passenger side fender area. That is where mine wore through. I cut out the bad part, put a clear hose splice over and was good to go!

I found it this morning. I wish everything was as easy of a fix and to find as that was!! After I installed aftermarket front bumper I tucked vacuum reservoir under the hood next to battery and the line came out of one of the elbows. Thanks for the help.
