Great solution!

Before you take it to the dealership, check your vacum hoses under the hood.
Just like the thread says, on the driver side, there is a line that get loose, perhaps because of motor vibration.
if you are not sure which line, is the one that runs just below the black plastic of your windshield, from one side of the car to the other( the driver side), patience and you will find it.
It will save you money, I didn't even had to buy anything.
cost $0.

However, my car was having starting issues, I have a clifford 590.2x installed, that is another story.
Had it rewired, that was costly ($325), hopefully I am good to go now.

Next issue, tranny...
Good luck to anyone fixing jeeps, they are fun.
